ever tried satellite pong, man? check this out, it's a great variation if you're good.
keep the standard triangles on the table, but on each of the four corners, put one cup full to the brim. if you get the ball in the cup, just like normal, then the person obviously has to drink the full cup. here's the thing, though. the "satellites" have no effect on the game. each time they get hit and drunk, they get refilled and put back.
lately i don't drink as much myself, so when i'm at a party my fun comes from getting some idiot blitzed off his ass.
