A, sometimes big, but flat and disgustingly sagging ass. Normally while fat black women just plain have big, round asses, most overweight white women tend to.
when ones butt has absolutely no shape to it at all. Looking very flat, like a pancake.
Also, for women quietly (or not so quietly) flipping their shit about their own pancake ass and the hate it's getting: it's really nothing to freak out about. Plenty of.
