When one cups his hands in the Ryu style of a "Haduken", but simultaneously farts and thrusts the vicious ball of stink into someones face. Variations include a slap at the end, taunting about the smell, and savoring your own brand while the person keels over from the horrible odor(s).
I will fartuken your ass after a vicious meal of beans, tacos, burritos, and italian cuisine.

Hater #1: "Dude, did you see that vicious fartuken followed by a haymaker"
Fake but scared fool #2: "yeah man, the hospital drove his ass away, he might make it"
