French form of slang/dialect where sylables are muddled around. The French film La Haine (a French gangster film) even had to have subtitles in French when it was shwon to critics who may not have been able to speak 'Verlan'. Verlan is verlan for 'L'anvers', which means 'reverse' in French. Almost every word in some poor parts of Urban French cities are spoken in this slang.
