it’s french, i asked my teacher, she didn’t know, couldn’t find it on the net. it’s from xavier collos movie 
It’s not french, it’s “verlan”. it’s a kind of slang: like “à l’envers” but reversed => versl’en à => verlan
“Vener” (or “véner” pronounce each letter) means “énervé” (angry).
I think a little click on the search button would have brought you the answer much faster than I did;)
Venir is one of the most common French verbs. It is irregular in conjugation and literally means “to come.” It is also used in some idiomatic expressions and to conjugate the recent past.
