The person starting this game must call out someone else, Then the other contestant must accept. Each person has 1 full keg cup and must finish that beer in 1 minute. Continue this process until someone cant finish the beer or they puke. After about 5 full beers in 5 minutes it starts to get a little sketchy. Happy drinking.
Hint: You dont always have to chug the beer right away, you have a whole minute to finish it.
