How about "me breath would set a fag alight" - in England, a fag is a cigarette. A few of us Brits were at Galax Old Fiddler's Convention in August, and my friend's use of the word fag confused a lot of people. He once said "I could murder a fag!" and a Texan nearby said "son, you're talking my language". His regularly referring to "rolling a fag" convinced everyone he was a homophobic mugger. Two nations separated by a common language.
