You will need a drink for each person playing (preferably beer). Players must have both hands!
The usual, you and your friends should be sat at a table or somthing similar.
This game is very simple, if any of the players get caught with your drink in your right hand, you must finish the drink off.
It is more fun if you try to get away with using your right hand without other people noticing. If any players are left handed, it would probably be best to use the opposite hand for that player.
