This game is just like poker. It might not be original but me and some guys made it up when we were really smashed.
Same rules as poker. Twos are wild and it's a 4 card draw, which means you can exchange up to 4 cards but here's the catch. For every card you exchange you take that many drinks and instead of betting money you bet a certain number of drinks.
You must go around the table at least one full rotation before you can call. If you decide to fold in this game you have earned the name pussy and you must finish your drink before the next hand is dealt. The object of the game is to bluff your way out of a bad hand. It's kind of a confusing game but it's fun.
