Ah, yes. I remember very clearly being warned as a medical student in the ICU not to refer to the ubiquitous Computers on Wheels that the attendings invariably stood behind and used as a podium and lectern as we did our "toilet rounds" (a term I'm sure is also banned) not to call them C.O.W.s, because some strange entity could be walking by just as the unfortunate 3rd year assigned to find the computer says, "hey, man, have you seen the cow? We're rounding soon!" and that troubled entity would undoubtedly be thinking, "hey, that asshole just called me a cow!" And of course would write a nasty letter to the administration about how terrible you are and should never be allowed to become a doctor. To avoid this tragedy, you should instead call them Workstations On Wheels, or W.O.W.s, which makes you sound like a moron.
