The 'Yo Mamas So Fat' meme is rooted in the long-standing tradition of 'the dozens'—a verbal game of insults popular in African American culture. While these jokes have existed for decades, they exploded into mainstream pop culture during the 1990s through shows like 'In Living Color' and later 'Yo Momma' on MTV. In the digital age, these jokes transitioned into image macros, often featuring a specific character or a stylized illustration to deliver a punchline about extreme size. The meme format typically follows a 'Yo mama's so fat...' setup followed by a hyperbolic comparison, serving as a staple of internet humor and playground wit.
