Super Smash Bros
Every time you kill someone they must take a drink. If they get knocked out the current game they must finish their drink.
If you kill someone with a pokemon they must take a shot and you get to nominate someone else to do the same. If any player is alive and has taken over 200% damage they get to nominate someone to take a drink.
If you kill someone with an Item they have to take a shot and the person who did the killing has to take a drink for the cheap shot. If a player falls off the map (This does not include getting kicked off into the distance) that person must finish their drink.
The last two players, have a fight to the death. The loser has to take a shot, the winner decides what it is.
If you win the game everyone else must finish their drink.
