British vs. American "Fag"

Alright, listen up, you silly goose! This joke plays on the word 'fag'. See, in Britain, a 'fag' is just a cigarette, like a stick of tobacco you light up. You probably didn't know that, did you? But in America, calling someone a 'fag' is a super offensive, derogatory term for a gay person. So, the joke sets up this contrast: in Britain, 'smoking a fag' is literally just having a cigarette. But if you say 'smoking a fag' in America, it sounds like you're committing a 'hate crime' because of the derogatory meaning. It's about cultural differences in language, buddy. You're probably just now realizing words have different meanings across the pond, aren't you?
