4B movement

4B movement, South Korean feminist activist movement and political stance defined by four deliberate refusals: bihon (“no marriage”), bichulsan (“no childbirth”), biyonae (“no dating”), bisekseu (“no sex [with men]”). These “four nos” constitute a radical rejection of the heteronormative, patriarchal life script traditionally prescribed for women in South Korean society. While the exact starting point of the movement is difficult to trace, it is generally understood to have emerged about 2015–16, gaining traction through digital communities and young feminist organizing.

Distinct from involuntary singlehood or the avoidance of childbirth due to economic precarity or other external constraints, 4B represents women’s deliberate withdrawal from patriarchal institutions, such as the nuclear family and heterosexual relationships, and a commitment to reshaping their lives around alternative forms of safety, solidarity, and personal autonomy. As scholar Gong Yeon-Hwa notes in her 2021 journal article “Escaping from the Class of ‘Women’: Reading the 4B Movement from Korea with the Theories of Monique Wittig,” this refusal extends into the symbolic and sexual economy of heterosexuality, with some participants forming lesbian relationships as acts of resistance—a complete departure from the normative life paths prescribed by patriarchy and the male gaze.

Connection to the Escape the Corset movement

The 4B movement emerged in South Korea alongside the Escape the Corset movement in the late 2010s, as part of a broader wave of popular feminist action among young women. These women shared deep frustrations over enormous pressure on appearance, workplace sexism, and everyday violence against women.

Escape the Corset emerged as a direct critique of socially imposed standards of feminine beauty and the labor and expense required to maintain them. Participants rejected practices such as makeup, cosmetic surgery, and hair styling, often documenting their transformations online by cutting their hair short, abandoning “feminine” dress, and destroying makeup products as symbolic acts of liberation. According to scholars Kang Mi-Seon, Kim Seong-Hee, and Jun In-Hye in their 2020 article “Writing My Own Life: A Qualitative Study on the Process of Forming 4B Values Among Women in Their 20s,” the movement sought not only external liberation from decorative labor but also internal freedom from socially gendered tastes, values, and behaviors, including hobbies traditionally coded as “feminine.” This double-layered effort toward bodily self-determination marked the movement as a critical intervention into the visual and affective regimes that regulate women’s appearances and desires.

While Escape the Corset addressed the physical presentation and surveillance of the female body, 4B pushed further into refusing the interpersonal and institutional relationships that perpetuate gender hierarchy—namely, heterosexual romance, marriage, reproduction, and sex. Together, these movements marked a decisive shift in feminist praxis from reformist agendas to more radical, lifestyle-centered strategies of resistance to dismantle the sociocultural expectations attached to femininity.

Rather than seeking institutional reform, 4B aims to transform gendered social practices through individual acts of refusal and withdrawal. Escape the Corset and 4B function not as mass organizations but as diffuse, decentralized collectives of women practicing media and hashtag activism, as well as new forms of feminist living. The aspiration to “live well as a woman” has become central in the movement—not in the neoliberal sense of personal self-help but as a feminist vision grounded in survival, dignity, and resistance to systemic inequality. What may appear as personal lifestyle choices are, in fact, deeply political acts and part of a larger effort to redefine what meaningful feminism looks like for a new generation.

Historical context of the emergence of 4B

The 4B movement did not emerge in a vacuum. It should be understood both as a continuation of and a rupture from earlier strands of feminism in South Korea—particularly the institutionalized feminism of the 1970s and the “feminism reboot” of the 2010s. Women’s studies entered South Korean academia in the mid-1970s, beginning with the introduction of a women’s studies course at Ewha Womans University in 1977. Through the 1980s and ’90s feminist consciousness spread across universities, supported by women students’ associations and culminating in the establishment of full academic programs by the 2000s. However, by the late 2000s the neoliberal restructuring of universities and the depoliticization of student life had led to the decline of feminist institutional infrastructure and the fading of campus-based feminist activism in the country.

This backdrop of retreat and disconnection gave rise to a new wave of feminist energy in the mid-2010s, often referred to as a “feminist reboot,” a term coined by Heejeong Sohn. Digital platforms, especially social media and online women’s communities, became critical spaces where young women exchanged feminist knowledge and built solidarity. While many young women still hesitated to openly identify as feminists—often prefacing their statements with “I’m not a feminist, but…”—these digital spaces began to shift that dynamic. The spread of feminist memes, personal narratives, and online campaigns laid the groundwork for a new kind of activism: everyday, decentralized, and digitally native.

Although the 4B movement lacks a clear founder or founding moment, its values—no marriage, no childbirth, no dating, and no sex with men—began circulating in 2015 in relation to Megalia, an online radical feminist community known for its use of “mirroring” tactics to expose misogyny. As Gong Yeon-Hwa notes, Megalia users parodied dominant male behaviors and declared they would not marry Korean men as a form of resistance. These digital declarations gradually coalesced into a political stance.

The movement gained further momentum after the 2016 Gangnam station femicide, in which a woman was murdered in a public restroom by a man who claimed that women had always ignored him. The incident triggered a nationwide outpouring of feminist anger, including a public sticky note memorial campaign. Young women began to understand misogyny not as an isolated or interpersonal issue but as a structural condition, prompting many to reevaluate their roles and relationships within heteropatriarchal institutions.

In December 2016 the government released the so-called “pink birth map,” a digital visualization that mapped municipalities by the number of women of reproductive age. Many viewed this as a blatant reduction of women to their biological capacity to bear children. Similarly, in 2017 public outrage erupted when a government-funded research paper attributed Korea’s low birth rate to women’s reluctance to marry lower-status men. The paper’s recommendation to subtly influence women into “hypogamous” marriages through media manipulation led to widespread protest and the slogan “We refuse to be fertile, we refuse to be livestock.” These events crystallized a shared realization: the threat was not just misogynistic individuals but a patriarchal state that commodified women’s bodies for reproductive purposes.

Later the revelation of a series of digital sex crimes further intensified feminist mobilization. These included the exposure and dismantling of the Webhard cartel, which revealed collusion between tech companies, content-filtering services, and so-called “digital morticians” profiting from the distribution of illegal pornography; the Nth Room case, which involved sexual exploitation through blackmail (documented in the Netflix film Cyber Hell: Exposing an Internet Horror, 2022); and the 2018 Hyehwa station protests, which erupted after police swiftly arrested and investigated a woman for nonconsensually photographing and distributing nude photos of a male model. This last case stood in stark contrast to law enforcement’s historically sluggish responses to egregious sex crimes committed by men—particularly, the widespread nonconsensual recording of women through the use of hidden cameras in public restrooms and hotels and on public transportation. The disparity revealed a persistent pattern of institutional bias and underscored the systemic danger women face in both digital and physical spaces. In this climate, many women viewed the refusal of romantic and sexual relationships with men as a necessary strategy for emotional and physical survival.

In 2017 the term 4B started appearing on the South Korean web portal Daum Cafe, where women began articulating a fourfold rejection: no marriage, no childbirth, no dating, and no sex. These acts were framed as strategic refusals of patriarchal life scripts. The 4B movement, then, represents a feminist politics that emerged from shared frustration, rather than abstract ideology. Participants in the 4B movement typically arrived at 4B through practical observations: witnessing the inequality in the marriages of friends or family members, encountering violence in dating and public life, or fearing the risks of pregnancy and sexually transmitted infections.

While influenced by the Young Feminist movements of the 1990s and early 2000s, participants in the 4B movement—often referred to as “young young feminists” or “digital feminists”—distinguish themselves through a more radical feminist politics rooted in refusal and disengagement rather than reform. Whereas earlier feminist organizations primarily focused on achieving legal and institutional reforms, they often failed to address the everyday precarity and marginalization experienced by younger women. In response to this gap, digital feminists asserted their lived experiences of frustration, fear, and exhaustion as legitimate grounds for feminist resistance.

Differences from the N-po discourses and earlier feminist movements

The 4B movement seemingly shares surface similarities with broader youth discourses of withdrawal in South Korea, such as the 3-po generation (“three give up generation”). However, it is conceptually and politically distinct. Coined by journalists in 2011, 3-po described a generation that had supposedly “given up” on romance, marriage, and childbirth because of economic hardship, unstable labor conditions, and widening inequality. Over time this discourse expanded into 5-po, 7-po, and finally N-po, indexing a growing list of social, economic, and personal goals young people were seen as abandoning under neoliberal restructuring. In this framing, the youth were largely depicted as victims of structural crisis. Non-marriage and childlessness were cast as involuntary losses. Within this N-po discourse, the institutionalized familism of Korean society remained largely unchallenged; the state and media continued to frame family and reproduction as normative aspirations deferred by economic pressure.

The 4B movement, by contrast, is not a reluctant retreat but a conscious ideological rejection. Feminists of the 4B movement are not giving up on the future—they are refusing to be used for the patriarchal state’s future, which they see as reproducing itself by exploiting the female body’s reproductive capacity through the institution of the family. In this sense, 4B is not resignation; it is resistance. While dominant gender norms continue to constrain the lives of unmarried women, 4B participants demonstrate the viability of voluntary non-marriage by constructing alternative, self-defined life paths that exist outside the reach of reproductive governance. While earlier feminists sought to reshape family norms and advocate for better conditions and policies for motherhood or marriage, 4B feminists challenge the legitimacy of those frameworks altogether.

Expansion to 6B4T

Over time the 4B movement has evolved into 6B4T, broadening its critique beyond gender to include capitalism and consumer culture. In addition to the original four refusals, the 6B framework adds two Bs. Bisobi (anti-consumerism; literally, “no consumption”) involves boycotting companies that sell misogynistic products or engage in sexist marketing. Bidopbi (unmarried women help other unmarried women; literally, “no help no”) emphasizes solidarity and mutual support among participants. As Gong Yeon-Hwa notes, these additions reflect a collective effort to resist conformity to existing social structures while cultivating alternative forms of community.

The “4T” components—tal-corset (“escape corset”), tal-jonggyo (“escape religion”), tal-otaku (“escape otaku culture”), and tal-idol (escape fandom culture; literally, “escape idols”)—further extend this feminist refusal into the cultural and economic realms, rejecting institutions and practices perceived as reinforcing gendered subjugation. Although 6B4T has not reached the same level of mainstream visibility as 4B, it has been actively adopted by young women on social media platforms, where it is used as a personal identity label and organizing principle. The framework has also begun to influence feminist discourse in China, marking the transnational reach of this radical refusal politics.

From online solidarity to offline communities and collectives

The political symbolism of unmarried women as feminist resistance predates the 4B movement. As early as 2007 and 2008, activists from the Young Feminist group Unni Network organized Unmarried Women’s Festivals to promote alternative communities and challenge the heteronormativity of marriage. However, as state and media attention focused on the aging population and declining fertility, the concerns of unmarried women were further pushed to the margins. Through the 4B movement, rejection of marriage has reemerged not only as a protest against the state’s pronatalist turn but also as a foundation for building new forms of feminist everyday life and community.

Despite the movement gaining traction online, some of its most powerful developments have occurred offline in local community-building efforts. Since 2018 a variety of community-based feminist collectives have emerged, such as WITH in South Gyeongsang province, BecomeTrue in Gwangju, EMIF in Seoul, and Bihonhugaem in Daejeon (an initiative of the BOSHU group in the city). These groups host feminist book clubs, invite guest speakers to give policy talks, and share practical knowledge such as home repair skills and hardware tool workshops. Some groups host gatherings for hiking, table tennis, football (soccer), and climbing. These 4B networks provide women with the knowledge and confidence to sustain life independently, helping them replace isolation with solidarity and community building.

Critiques and controversies

The 4B movement has not been without controversy, drawing criticism from both conservative and feminist circles. From the political right, it has been attacked as selfish and antisocial; Protestant groups in particular link 4B (especially bihon, or “no marriage,” and bichulsan, or “no childbirth”) to South Korea’s low birth rate and portray it as a threat to the gendered social order. These attacks build on a long-standing pronatalist narrative that predates 4B, in which conservatives have consistently framed low fertility as the result of women’s “wrong” choices and sought to regulate women’s reproductive lives. Since the mid-2000s, church-affiliated organizations have campaigned against abortion while promoting pro-marriage, pro-childbirth policies. With fertility below 1.0 (meaning that women are having, on average, fewer than one child each) since 2018, the Yoon Suk-Yeol administration declared a “national population emergency” in 2024 and proposed measures such as expanding flexible work arrangements, encouraging fathers to take parental leave, and increasing access to public childcare. Conservatives thus cast 4B as emblematic of anti-family values, accusing it of fostering misandry and deepening gender conflict.

Yet the movement has also generated tensions within feminism itself, particularly around issues of biological essentialism and the exclusion of trans and nonbinary people. A central point of contention lies in the strong identification with cisgender women expressed by some feminists within the 4B movement. Trans-exclusionary radical feminist (TERF) tendencies—referred to as RadFem in South Korea—have been especially criticized by queer, trans, and nonbinary individuals, as well as by intersectional feminists who advocate for broader gender inclusivity and solidarity. Intersectional feminists argue that both RadFems and anti-feminist backlash actors share binary logics, categorizing feminism and women into “real” and “fake,” or “true” and “false.” This tendency was evident in debates over the Escape the Corset movement, where some RadFems began compiling ranked lists distinguishing “real” from “corseted” looks. Similarly, anti-feminist forces deployed the same binary to undermine feminist legitimacy. These critiques suggest that, while 4B has succeeded in igniting a radical and resonant feminist movement, it has sparked debates about inclusion, coalition building, and the dangers of re-essentializing womanhood.

Attention to 4B in the United States after Donald Trump’s 2024 reelection

The 4B movement has gained notable attention outside South Korea, particularly in the United States following Donald Trump’s 2024 presidential reelection. Amid renewed anxieties over reproductive rights, conservative backlash, and the erosion of gender equality, many young liberal women in the United States began citing 4B as a compelling model of feminist resistance—embracing its ethos of opting out of patriarchal institutions. On platforms such as TikTok and Instagram, 4B slogans circulated widely, with users referencing South Korean feminists as inspiration for rejecting heterosexual romance, marriage, and motherhood altogether.

At the same time the movement has also drawn criticism. Observers questioned the sustainability, applicability, and inclusiveness of 4B’s politics in the U.S. context, with some echoing earlier critiques from South Korean activists who described the movement as homophobic and trans-exclusionary and noting that the movement was born out of and shaped by the specific gendered and political context of South Korea.
