look up any word, like pussy:
 
1.
Noun: Fart Star (fährt-stär)

A large amount of flatulence with a minimum of a 0.05 solar mass, that collapses in upon itself and ignites into a ball of stinky plasma.

Contrary to popular belief methane which would be incapable of becoming a star on its own is actually a minimal ingredient in a fart. A fart mainly consists of Nitrogen, carbon dioxide, and Hydrogen which given enough could in fact condense in upon itself and ignite into a star.
According to science it's theoretically possible for a fart star to come out of your ass.
