Jungle juice is the name given to an improvised mix of liquor that is usually served for group consumption. There are countless recipes and even websites devoted solely to jungle juice. The term has also been used for similar less-than-reputable alcoholic concoctions.
There are several popular explanations regarding the origin of the name. Generally, it is believed that the name originated in the South West Pacific theatre of World War II, where American soldiers improvised such a concoction using any commonly available materials in the surrounding jungles for fermentation, distillation and flavoring.  Alternatively, it has been suggested that the name comes from the drink's potency, causing an extreme state of inebriation and thus causing the drinker to exhibit animal-like behavior. The characteristics of this concoction leading to its legendary status are its relative inexpensiveness and potency.
