Listen up, buttercup. This joke is all about exaggeration. Yo mama is so fat, when she sits, it's like an earthquake! Earthquakes are measured on a scale, and 7.4 is a big one, meaning this joke implies Yo mama is REALLY fat! Get it? Of course not, you're probably as dumb as the person who wrote this joke.
