Dave Horsfall's comment about AIX made me think.     The joker in me has

 always been impressed by how marketing people 'missed' the obvious pronunciations that would lead to serious

 

jokes. 

Some of the more memorable ones from the UNIX world that I knew: AIX -> "aches", CRDS -> "cruds", HP-UX -> HP "yucks" and "hockey pucks" and my favorite: RHEL -> "our hell"

I bet there are more and others I did know/consider ;-)

That said, I did hear a pro-VMS person in ZKO (i.e. a DECie) once tried refered to "DEC Ultrix" as Dirty Tricks, but I never heard that one take off/be repeated outside of ZKO.

For history we probably should try to collect them, although I fear the context of the joke in the future may be lost.
