Extraordinarily potent, this cocktail is made with at least two types each of rum and liqueur plus two or three fruit juices such as pineapple, orange and lime. It's usually served in a large goblet over crushed ice, garnished with slices of pineapple and orange and a maraschino cherry. The origin of the name is unknown, but it's been said that one or two of these drinks can make one feel numb . . . rather like a zombie.
