Outside Britain, swearing is ONLY for the lower-working classes, the very drunk or the insane. I've lived and worked in America, France, Greece (and for short periods in other places) and in the workplace or out in everyday society you just don't hear people swear.
In Britain, if an email bounces back, anyone, the secretary or the CEO of the company would easily and without a second thought say "wanking fucking email - I fucking hate these fucking computers... Bastard computer cunts are running the whole fucking world". If you did this in a US political office people would feint and you'd be fired three minutes later. In France things get "badly broken" while in Britain they get Royally Fucked Up.
Personally, I like it... It's like having a whole second set of vocabulary to play with. I can say "broken" when I need to just as easily as any Frenchman, but when I need a little more I can say "Fucked up like a fucking stupid fucked up piece of shit that's just been fucked over by a fuck grenade full of shit".
I love that and it's OK because people around me will neither freak out or even be surprised.
I rarely use "cunt" though and I think as a society of swearers we've reserved this word for only the worst (or best) of occasions and that makes sense.
If you want a real handle on all this stuff just read "A clockwork Orange" which delves into it and plays with it all brilliantly.
Anyway, piss off you bunch o' cunts, I'm going the fuck to bed.
