A shit that has a fart stuck in behind it.

When you go to the toilet with a rocket-powered shit, the result depends on the type if shit- if runny, it will erupt and spray everywhere, covering the toilet bowl in modern art. If dry, all the shit will force itself from your anus in one log, leaving no mess behind, and creating a huge splash as it cannons into the water. A rocket-powered shit will need no wiping after, as the fart cleans it all up for you.
Bob: dude I need to go take a shit
John: cool man tell me how it goes

(Explosion and subsequent screams emanate from the vicinity of the bathroom)
Bob returns.

John: oh god, what have you done?
Bob: fuck. That shit was no ordinary shit.

John: oh my god
Bob: it was a ROCKET-POWERED SHIT
