Great drinking game, where there are two teams who race to drink there beers and flip their beer cans. Teams go in a line, first team to get all can flipped and landed win.
Practice popular at raves of taking ecstasty and LSD simultaneously. (A British band, Candy Flip, popular in the 1990s, was named after this practice).
It looks like EVERYONE here, except the cops at the doorway handing out water, did a candy flip.
