A bad looking ass that forms a V shape with the butt cheeks. Often associated with asses from the 80's or a flat ass. Can often be seen in sweat pants or stone washed jeans. Also known as a saggy butt.
I saw a chick at the bar with a disgusting Vass the other night!

Vass is the backbone of greatness... and a really cool name to have on your t-shirts... Stems from the name Vassilios.
Vass is an awsome guy.

If your taint is missing what you would call the vagina/asshole that is there.
The girl with no legs, also lost her taint in the accident, but guys still fuck her vass.
