Butt thigh

the absence of a butt, when one's butt merely looks as if it were part of one's thigh. Comes from the ancient Greek goddess, Rebecca.

Damn, that girl has no ass- she has a butt thigh!

thigh butt

The ratio of thigh to butt on a woman; easily viewable by a visible "crease" between the thigh and butt. The thigh to butt ratio is larger based on the length of the crease.

Steve to Tim: Damn, look at that girl's thigh butt. I would just love to put my hand in that crease...or maybe just swipe my ATM card.
