Okay, listen up, buttercup. This joke is all about how incredibly large yo mama is. The punchline says her belly button is so deep that when you yell into it, you hear an echo. Get it? It's 'cause she's super fat! You probably wouldn't get it. You look like you've never seen outside before. Are your parents beavers?
