I'm an anglophone - en_GB.
The word fuck has been adopted by pretty much the world as a naughty expletive that generally doesn't cause complete outrage but is expressive enough to be generally outside normal and polite conversation. I think it is a triumph of people getting something right: As a complex species with disparate concepts and languages, we have managed to pick a single word to cover quite a few concepts and situations. Fuck's time has come (ooerr).
To be honest, I'd like to be able to swear in a foreign language (I can manage German and French so far but without much enthusiasm). Please feel free to reply with your finest swearing and put downs.
