I like this. I laughed out loud.Well, here's a (not so) good insult I just came up with that, uh, makes a reference to something very old.
"Yo mama so fat she's bigger than the Venus of Willendorf!"
The Venus of Wllendorf is actually like a few inches tall I'm sorry

If you said fatter than the Venus then it wouldn't matter that it's 2 inches tall.
