Buffalo or Buffalo Club is a drinking game where participants must chug their drink if they drink with the wrong hand, usually the player's dominant hand. In some versions, merely holding a drink in the right hand is an infraction (Strict Buffalo). Buffalo is commonly understood to continue for the players' entire lives. People who play the game refer to themselves as "Buffalos", and groups of players may refer to themselves as a "Buffalo club", though the game itself is also sometimes called "Buffalo Club".
