When two dudes, who are down to pound, bump their buttholes together in order to reach a mutual climax. This would be comparable to when women participate in what is called scissoring, where they smash the vaginas together until the juice comes out, but in this case.... It's just poop.
A sexual act, commonly done by sucking the cum off of a man's dick from the tip only like an Indian pipe circle, putting one's face towards the sky and spit-taking it like smoke or mist.
Usually done in prison. When you put a pipe next to your anus and put a rat in the pipe. You take a lighter/heat the bottom of the pipe, causing the rat to scurry into the anus. It scratches as it suffocates, causing pleasure in the individual.
“I always triple glove when giving rectal exams to prisoners because of worries over piping.”
