Sake is an alcoholic beverage of Japanese origin made from fermented rice. Often referred to as rice wine. Sake can be served either warm or cold. A sake bomb is the act of quickly consuming both beer and sake at once. A small sake cup is precariously placed on two chopsticks on the top of a drinking glass that contains beer. The words sake bomb are yelled at the same time the table is pounded with the drinkers hands. When the small cup full of sake falls into the beer, the drink is pounded (to drink very quickly).
