THASS

A mammoth, massive ass that spills wide and heavy onto the back of the thighs.

Lamont: Yo' Mell, look at the ass on that stallion! Unh....its so damn big, I can't believe it (stares in atonishment)!

Mell: That ain't no stallion! That's Schwalla. Her swoll thass makes her waddle when she walk.

(both laughs out loud; grab/rubs nuts)
