This is a alcohol drinking game, which requires two things, a in n out water cup (with the lines around it) and alcohol(preferably goldschlager) So you pour your alcohol in the cup. and amongst your friends you play rock paper scissors to see who has to suck it up. For every line on the cup the losing person takes that much alcohol, and for the big ones then the loser gets fucked. Chase it down with french fries, water, and soda.
