Thut

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.
