%$@$!!

I don't like it when my co-workers use four-letter words around me. So far, I've managed to get them to reduce the frequency when I'm around, except for a younger guy who feels that profanity of some kind is necessary in order to vent.

He finally agreed that when he wants to swear, he'll at least do so in a language that I don't speak so that I am not so easily offended. After a short brainstorm in the room on languages I don't speak :D, we came up with Klingon.

Today, I've heard him use petaQ twice already... which is certainly better than English four-letter words, as far as I'm concerned :) (That word is glossed as "%$@$!!".)
