Common French Slang?

[gen]

I know in the United States, people and (mainly) teens, use slang terms. I'm curious to know what some of the common French slang terms are.

there are 2 things in France; first slang as such (if I have time I shall add a few) we also have Verlan which is an argot in the French language, featuring inversion of syllables in a word, and is common in slang and youth language. which would baffle a few people a simple example would be "bonjour" which is verlan is "jourbon"
