Thass

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

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.
