citispeak
A broad term encompassing numerous variants and 'dialects'. Citispeak is a group of modern hybrid 'languages' born from the amalgamation of numerous traditional tongues. These strange conconctions are thought to result from rapid immigration into crowded urban areas. Components of the mother tongue of these migrants were assimilated by the local populus and merged with colloquial slang etc. to produce 'citispeak'.
One of the most famed examples is that of 'Gaff' a character in Ridley Scott's 'Blade Runner' motion picture, whose citispeak is a mixture of languages including fragments of hungarian.
