Shart rocket 

A small cork-like turd that is expelled from one’s ass (much like popping the cork off of a Champaign bottle) during the act of farting.

Sitting on the toilet
Jorge: “phoph pfffffffhhtt.”

Jorge: “wtf that little shit just shot out of me like a mento from a fizzy cola.”
Jorge: “ sweet mother teresa that there is what I call a Shart rocket.”
