A thut is an unfortunate condition where a the back of a woman's thigh and her butt have become a single entity. There is no sudden incline from the back of the thigh to the farthest part of the butt and it becomes more of a slope.

It's caused by a lack of glute muscles.
It's a treatable condition, it is generally cured by squats and other glute exercises.

You can figure out if you have a thut by putting a pencil between where your butt ends and your thigh begins. Stand straight and somewhat tighten your glute muscles. If the pencil falls you're safe. If it stays...I'm sad to inform you that you have a thut.
"She was wearing a bikini, and it would have looked good if she didn't have a major thut."
"I used to be so hot, until I got a thut."
"Look at her thut, she really needs to get off her ass"

"Her thut was so loaded with cellulite it looked like cottage cheese packed into a condom"

when your butt blends into your thighs, or there is just no definition between your thighs and your butt, you have a thut (thigh-butt).

guy 1: "...ya nasty..."

A contraction of the words "thigh" and "butt". Used to denote the area on an old or morbidly obese girl's ass where the buttcheek meets her leg where either advanced age or fat has removed the nice shapely division between these two body parts and replaced it with an area where the buttcheek and upper thigh join into a single homologous lump. Said girl will also normally have a massive FUPA. Similar to kankles.

OR a derogatory way a pretty girl who THINKS she is overweight talks about her own ass.
1. Oh gross, don't look now but that girls thut is hanging out of her swimsuit...oh gross, its like a pastry bag filled with cottage cheese...*gag* 2. Babe? Do these jeans make me look like I have a mom-ass or a thut?
