That's where the English language and American English gets mixed sometimes i guess.
I always remember when i was younger i was on a family holiday to Florida and my Mother said in the restaurant she was going outside for a f ag. She got some funny looks from everyone in the restaurant that's for sure.
F ag = Slang term for Cigarette (in case you didn't know)
I even had to put a space in the word cos wgt stared it out...lol
