A combination of the words flatulent and vigilante, flatulence meaning of course, the act of breaking wind (farting), and vigilante meaning a person who is not in law enforcement, but tries to bring criminals to justice (motherfucking Batman). A flatulante then, is someone who punishes criminal or incredibly tasteless behavior with a fart to the head or face.
Dude, did you hear about the guy who farted on a kid's head in a superstore because the kid was being a shithead to his mom? That guy is the very first flatulante!
