Troopers of the PNP Special Action Force refer to their wives as Alpha and to their mistresses as Bravo, probably all the way down to Zulu.  This is a very practical way of doing away with names, but is also very obvious.

That, and the datkilab/tadbalik quasi-language pretty much prove that, as a people, discretion is not our superhero ability.
