look up any word, like dirty sanchez:
The act of sculpting a fart into an object, weapon, or other destructive device with intentions of harming the farter with it.
Billy: *Lifts ass to aim fart at Johnny* "lol I just pwned you"

Johnny begins fart sculpting *Takes Billies fart mid flight and shapes it into a fart RPG, which he then fires back at Billy*
