I can't say that I tut much. These days I tend to sigh and go 'fuck's sake!' instead.
A couple more Americanisms I remember:
Faucet = tap (in a sink) Restroom = toilet/loo Communists = anyone living in a country that offers some sort of social benefit (Ok I may be exaggerating here, but I had my Texan ex-sister-in-law try to tell me the UK was essentially a communist country once. I did laugh.)
