A girl's ass that is fat, not just big, but a booty that has a lot of jiggle to it. A blubber butt should contain some cellulite and cottage cheese and always fill up the girl's pants. Nothing is better than a blubber butt, it is a godess-like feature on bbws that is a true thing of beauty.
My girlfriend's blubber butt looks damn good in a thong with all her fat hanging out, I get an instant hard-on from looking at it.
