tuck ass 

A perfect ass which tucks at the bottom which distinctly separates the the bottocks from the upper back thigh. It cannot be found on a male individual. Tuck ass can be so powerful it can cause uncontrollable twitches much like epileptic seizures, and also makes one yell "TUCK ASS!" in a very stereotypical southern accent with a slight stutter.

hell yeah! that TUCK ASS made me have an epileptic seizure and yell in a stereotypical southern accent with a stutter!

asshole tuck 

When a male tucks the head of his penis in his asshole and squeezes his anus to hold it there while walking around.

A technique usually found in use by transvestites attempting to hide their gender while stripping.

I was getting the best lap dance from this stripper until her asshole tuck gave way.
