Now that you mention it, American don't get swearing. I don't like hearing them swear either. Americans swearing never sound cheeky, charming, witty, good humoured, playful or anything like that.

I had an American friend at Uni who used to try local swearing or idioms from time to time. "Bloody deadshit!" "Ya reckon?" Relatively tame in the context (bars) he was trialing them. He could never pull it off smoothly, it always got him funny looks. The French, Arab or even Chinese could do it. It sounded fine. Not this guy.

I wonder what makes it like this.

No wonder you ban swearing in The States.

Edit: No malice intended.
