When craters can be seen in a girls booty from it being too fat.
My mom has the nastiest cottage cheese ass.

A person with an ass so cellulite ridden, that the ripples of fat resemble curds of Cottage cheese. An extremely flabby ass.
I thought Sarah had a banging booty, but when I finally got her naked, I realized that she had a Cottage Cheese Ass.
