I'm sure you can find a naughty word or phrase, or some other semantic collision, out of almost any 3-letter combination, in some language somewhere. Sure it's one of the more well known ones in a very common lingua franca, but we humans are smart and can context switch.

Edit: Actually not sure if you are talking about Point of Sale, Place of Service, Piece of $#!7, or something else. Case in point: context matters.
