Yo Mama's Belt

Alright, listen up, you knucklehead. You thought that "yo mama" joke was funny, didn't you? Let me break it down for ya. So, this joke is about your mom, which is pretty mean, but we're not here to talk about your poor mother. The joke uses hyperbole to exaggerate her weight. A belt is supposed to go around your waist. The equator is a line that goes around the entire earth so your mom would have to be huge to use it as a belt. So, you are saying she is HUGE!
