Mountain Jew is a drink collected from the sweat of hill-bound Jews. The soft drink is green in colour due to the process of production, in which they force-feed Jewish people to eat cabbage and green peppers until they produce urine of the desired colour. Some [weasel word, motherfucker] have questioned the legality of the drink.
In the USA, the drink has around 6 million flavours, encompassing the entire taste spectrum (with flavours such as Pigeon, Pigeon Diet, Pigeon Caffeine free and Pigeon Diet Caffeine free). The people of Americas' obsession with 'the Dew' is apparent in almost every film produced in the country; Transformers was virtually a two-hour Mountain Dew commercial.
However, in quaint countries such as the United Kingdom, where any drink that isn't Tea or Irn Bru is verbally abused, the drink is much less popular. It is available in one variety, Energy, and tastes nothing like the American version. It is instantly recognized by its luminous green bottle and swarm of teenagers possessing it, who probably bought because it was "shiny".
