Foreign profanity exchange

Here's a newsletter or a Web site where people can exchange profane words and phrases in a variety of languages. Knowing how to swear in a foreign language can make you seem sophisticated, well-traveled or at least give you a means to swear in front of others without them thinking of you as the foul-mouthed person you really are. It can also provide cocktail-party type conversations ... impress you friends by informing them that one of the worst things you can tell a French Canadian is that you're going to "Christ" them to death, or that in one of the Balkan countries (Croatia?) one of the worst things you can tell a person is "Your mother is Easter." (And if those things I've heard prove untrue, why then this exchange can debunk said myths.)
