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.

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 Pistol 

A water pistol loaded with diluted fecal matter.
Helpful when heart-felt revenge is in order.
Not a recommended course of action in many circumstances.

1: "Man, I cheated on my wife and she soaked me with the shit pistol"

2: "Hey! That lady just hit my car and drove off, I'm gonna chase her down and spray her windows with my Shit Pistol."

shot in the face with a shit-pistol 

Extreme ugliness. Maybe be from acne or acne scars, or just plain old hard livin'.

You took home a chick last night that looks like she was shot in the face with a shit-pistol!
