Well Kan-Jam is like the thing to do at my college.
Its the only thing as popular as pong.
It is probably gonna sound stupid but its great at parties.
You have two "Kans" and your team mate is about 50-60 feet away from you. You then take turns throwing a frisbee towards the kan and having your partner try to hit it in. You get one point if your partner hits the Kan, two if the thrower hits the can, 3 if your partner hits the frisbee into the kan and an automatic win if the thrower can get the frisbee to go in by himself.
You go to 21 points and like I said its tons of fun. You can have a lot of games going on.
