we allways play 'i never' (insert something you have never done) then if other people have done it they drink, but you can also lie but if somebody knows your lying then they call you on it and then you have to drink a disgusting concotion of drink lol.
'drink while you think' is also a good un we usually use famous people beginning with the last letter of the persons name EG me tom cruisE next person Elijah wood until you cant think of one and you have to drink the disgusting drink again!
