A very disgusting sexual act where a guy shits in a cup while squeezing it in between his ass cheeks. A girl will then grab the cup with her teeth and either flip it in between her legs, on the guys balls, or upon her head.

If a girl is a flip cup champion, she can flip the cup between her legs then onto her head, and finally on a guys balls.
Guy 1: What did you do with that chick last night?

Guy 2: We played flip cup... and not with liquor.

Guy 1: That's nasty man, don't bring her home to your parents.
