Interesting that this is an actual phenomenon. I recall my French friend explaining to me that "McDonald's" was shortened to "MacDo" which then (if you were in the know) was reversed to "DoMac".
It is pretty old, it was already popular in the 90ies when Les Inconnus used it. Everyone who wants to appear « in » (in touch with the young) uses it, I’m not even sure it looks that cool to actual teenagers ;)
Teenagers may learn some of these words without realizing it's verlan. For example a strange/weird object can be "chelou", it means bizarre or surprising now, it has lost the semantics of the original "louche", meaning suspicious.
Imagining Jobs getting a bit nervous about this.
A Mac wouldn’t be confused with a McDo because both are short enough that they can’t be shortened.
