French language game involving reversing syllables in a word

Verlan (French pronunciation: ​[vɛʁlɑ̃]), (verlan is the reverse of the expression "l'envers") is a type of argot in the French language, featuring inversion of syllables in a word, and is common in slang and youth language. It rests on a long French tradition of transposing syllables of individual words to create slang words.[1]:50 The name verlan itself is an example: it is derived from inverting the sounds of the syllables in l'envers ([lɑ̃vɛʁ], "the inverse", frequently used in the sense of "back-to-front"). Some verlan words, which are now well incorporated in common French language, have taken on their own significance, or at least certain connotations that have changed their meaning.[4] For example, the word meuf, which can still be used to refer to any woman, also refers to the speaker's girlfriend, when used in the possessive form (ma meuf → my girl); while the original word femme would refer to the speaker's wife when used in the same way (ma femme → my wife).
