There's supposedly also an Italian pun based on "vero" in there.

I've heard pretty much every European English-as-a-second-language speaker pronounced the W differently, though, and pronunciation of the E isn't even consistent within native English populations. I can't wait for the "vee-ro? oh, you mean whay-ro" discussions between tourists and stores.

It will for sure be pronounced Véro in French :)

Ouiro does sound pretty ridiculous to be honest
