"Icing" -- or "getting iced" -- is a frat star drinking
game. The rules are simple: If a person sees a Smirnoff Ice, he or she must get down on
one knee and chug it, unless they happen to be carrying their own Smirnoff, in which case they can "ice block," or refract the punishment back onto the attacker. However, an "Ice-block-Re-Block" is when the original attacker is in fact carrying two Smirnoff Ices and anticipates getting Ice-Blocked. In this scenario, both players must get down on
one knee and chug it, hereby putting an end to
the game (to avoid further blocking).
