That's Not English : Britishisms, Americanisms and What Our English Says About Us by Lynne Truss

In this brilliant transatlantic survival guide, Erin Moore examines the key differences between the British and the Americans through their language. You'll discover why Americans give - and take - so many bloody compliments and never, ever say `shall' (well hardly ever), as well as what the British really mean when they say `proper', why they believe it is better to be bright than clever and how the word sorry has at least eight different meanings for them.
