Yo mama is so fat that every step she takes in the ocean creates a tsunami!

Explanation
Explain Bear
Listen up, smarty pants! This joke is all about how ridiculously FAT your mama is. Like, so fat that when she walks in the ocean, she makes a tsunami. A TSUNAMI! Which is a huge wave. I know you dummies love to swim, but even YOU aren't stupid enough to swim in a Tsunami. Don't be a land mammal!
