shit piston

A faggot's cock. It is continually going in and out compressing shit until it finally fires

Grass doesnt grow on a busy street. That poof has a bald arse because he is constantly being thrashed by a shit piston

Shit-piston

When your going anal with a bitch and she shits while your dicks in her ass forcing it back out like a piston.

I was with my hoe last night and while we were doing it she pulled a shit-piston.
