Count on me for all your slang translation needs. I'm bilingual... I speak both British and American English. Benefit of living in the UK for a year. Actually, I speak some Canadian too, courtesy of my mum.
Lived in Oxford, went to middle school there. My dad was teaching at Nuffield on sabbatical. We did do some traveling: York, Bath Spa, London (of course), took holidays in Cornwall and the Isle of Wight. And naturally we popped over to the continent a few times as well.
