Call of Duty
2 or More
Players sit around the console and you enter any online game type, single player. For every kill you get the person to your left takes a drink. Once you die twice you pass the controller to the person to your left.
If a person gets more than 5 kills it changes direction and the person to your right drinks and you pass the controller to your right instead. For each perk used you must take a drink yourself, worst perk is 1 drink for every perk that is better it is +1 drink. If you get a head shot you can nominate anyone to finish their drink.
Count your kills and the person who got the most at the end of the game gets to nominate someone to take a shot.
