Actually, having lived in both the UK and America, I can say there are a LOT of British people that speak retardedly…they are called Chavs…and you all know this. Even more retarded than many Americans. So Sarah is right.
I think Sarah said British because in the US, people don’t usually say something is “crap” in that context. Someone wouldn’t say “I did crap on that” in the US, whereas in England, isn’t it common to say something along those lines?
