Smirnoff Ice

A malted beverage (hence not a vodka like other Smirnoff products) that one is forced to drink when presented, usually in some ceremonious fashion at a large gathering, in an act called "Icing." When iced, the drinker is required to get on one knee and chug the entire bottle, despite occasional jeers, jokes, discouragement and/or encouragement from onlookers.
