There was a video in the late 90s of a young guy from parisian suburbs talking about how Verlan (the language of his generation) jumped the shark.

His quote was something like:

   > First we started with 'arrete ca' (stop it), 
   > then 'te-arr ac', then one guy's gonna say 'te' ..
   > surely one day it's gonna be 'et'. 
   > I swear, if someone says 'et' to me, 
   > I'll grab his collar and yell 'ARRETE CA' immediately.

I found the rare distance over its own generation priceless.
