VERLAN = LANVER = l'envers (meaning "the reverse").
Verlan is formed by inverting syllables. As with many language games, Verlan suffers from the fact that it is primarily a spoken language passed down orally, and thus there exists no standardized spelling. While some still argue that the letters should be held over from the original word, in the case of Verlan most experts agree that words should be spelt as to best approximate pronunciation, hence the use of "Verlan" as opposed to "Versl'en".

(One of the reasons that Verlan has not caught on in America is precisely that French, as a language, has syllables more conducive to inversion from an aesthetic standpoint)
A caveat about Verlan is that different rules apply when dealing with one-syllable words. While this may vary between dialects, there are certain words which are usually inverted or not. Words like "très" remain unchanged in most dialects, while "femme" is usually inverted.
Verlan spoken in real has also incorported some non-french words (mainly Arabic words).
