Ice luge

[3][4] The Routledge Dictionary of Modern American Slang and Unconventional English defines Ice luge as "a block of ice used in a drinking game in which a shot of vodka, tequila, or other alcoholic drink is poured down the ice into the drinker's mouth.

[5] Some designs incorporate the use of a tube that exists within an ice sculpture.

[1][5] Typically liquor, such as vodka,[7] is poured into a channel at the top of the luge and dispensed at the bottom of the channel, either into the mouth of a participant or a glass.

[2] There is a possibility that vodka may be diluted with water when ice luges are used[7] (along with other beverages).

Martinis and champagne are also sometimes chilled and served using ice luges.
