Your Mom

Alright, listen up, buttercup. This "yo momma" joke is like a playground classic, but with a twist. The bully starts with the usual insult, but BAM! The girl hits back with a zinger about the bully's dad getting cozy with her mom. It's unexpected and kinda savage, which makes it funny. Also, calling your mother a "girl" when the bully probably meant for her to be old is a funny contrast. You probably wouldn't get it 'cause you're not the sharpest tool in the shed. Facts, not feelings, kiddo.
