A challenge where by one must; get drunk, get stoned, get with an Asian (far East Asian e.g. Chinese) then pass out on the stair-case all in one night.
Named in honor of Charlie Sheen.
Note: Anyone else attempting the Full Sheen must buy the victor a gift as a token of his (or her, if she's into that sort of stuff) submission, such as a customised Championship Wrestling Belt.
Guy 1: "Hey, Look! Huang made it!"
Guy 2: "You going for the Full Sheen tonight?"
Guy 1: "Yeh, as long as Barns brings the 'stuff'."
