Why does slang often lose its impact after it becomes widely used?

Slang often loses its impact after becoming widely used because its effectiveness relies on being fresh, distinctive, and often shocking. Much of slang's power stems from its ability to create incongruity or social satire by applying novel, vivid imagery to established concepts, often in ways that challenge the values of the dominant culture.12

When a term is adopted by the masses, this "shock value" is diluted. Excessive use tends to dull the luster of even the most descriptive phrases, eventually rendering them "flat" or "dead". Furthermore, because slang is frequently used to promote solidarity within specific groups—particularly age-based subcultures—it must remain exclusive to maintain its function. Once a term enters the standard vocabulary or becomes common in mass media, it no longer serves as a unique marker of group identity, leading to a high turnover rate as new, more effective expressions are sought to replace the old ones.321
