Toilet seat ass

When someone’s ass has a V shape to it and is very flat like they sat on the toilet all day.

“Dude, the lunch lady has got some nasty toilet seat ass in those tight clam diggers.”

Louise screamed at the kid for giving her a $20 bill for lunch and she walked away with her V shaped flat toilet seat ass.

Uncle Henry’s toilet seat ass is noticeable in any pair of jeans he wears because it excentuates how flat and V shaped it is.
