Shelf ass

Noun: a butt characterised by the sharp right angle from one's back, to the top of their ass. The thighs blend straight into the booty, but somehow it is very distinct from the back. It looks like they sat down for so long that their ass flattened out. The sharp angle makes it look and act much like a shelf.

"My teacher has a shelf ass so big that you can stack books on it."
