What are some common French slangs used?
what are words or phrases French teens are using these days? Please include the meaning and how it's used. If you know of a site that's a slang dictionary like urbandictionary.com, post it, pretty please.
Also, I looked up about verlan, a form of French slang. Can someone explain more on how to use that? I googled some info. on it...I know that I'm supposed to separate the syllables, reverse it, then put it together. Does it work every time for every word? What happens if it's more than two syllables? If I speak using verlan, do I manipulate almost every word in a sentence? or just certain words that have a certain number of syllables?

Answer

Salut Maryjane,
Verlan comes from l'envers ( meaning reverse) 
If you seperate its syllables : l'en vers  then reverse them  it becomes  vers l'en ,with omitting unnecessary letters "s" and modifying the "e" it becomes : Verlan.
This goes for most 2 syllable words like for example :
bonjour     bon    jour        jour   bon     jourbon ;)
femme     fe        mme      fa      meu ( how it is pronounced),
by reversing it becomes : meu    fa   
omitting the "a" it becomes  meuf ! and so on 
Words like "à" couldn't be reversed of course , while "en" ,"au" ,"il" are not likely to be reversed .It is not that simple, because there are many modifications that follow no certain rule and you can know them by heart if you practice using that language.
It is spoken in french sometimes.A native french will certainly give you a better idea..
