Oh dear oh dear <shakes head>
First of all it's twat not twit

(another word for cvnt)
And yes we have a much more liberal culture towards swearing than you poor americans do, it's not that big a deal they are only words after all. I still can't believe you have to censor words like crap and damn on TV, that'd be laughed out of the censors office over here.
One word we tend you use a lot as a swear word over here is piss which I believe you guys don't consider to be one

i.e. "piss off" or "I'm so pissed off" etc.
Wanker is a favourite as well though only cockneys pronounce it waynkar. Another favourite would be Boll0cks and fvckwit
There are many more but I can't be bothered to think of them at the moment
