look up any word, like wrapped up like a douche:

Where a behemoth-like lady/midget (could be a midget they aren't something we types call "very well heightened-off-the-ground". And in due to such circumstances, these ladies legs turn from fat uhh fater. So-so-too many hungry man's.
It's where some most likely depressed 50 yr old gives up and gets so fat where the fat ass thigh merges with the fat ass.
AKA THASS.
Thigh/Ass = fat thighs merging together with the fat ass.
Looks like zeus mixed with the kragon from clash of the titans.

thass; the area in which your ass and thigh join as one. there should be definition between the two, a thigh... then your ass, creating a "shelf" if you will. but when you start to gain weight you loose that definition, thus creating the infamous thass.

"Look at the thass on that!"

Thass; the thigh / ass crease or more importantly the lack there of.
Her ass has become one with her thigh , where there was once once a seperation there is no more.

That small area on either a male or females body,that is right between one's ass and one's upper thigh,could be the crease or just that area that on some people just blends together.
Oh that hurts, a spider just crawled up my leg and bit me on the 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.
