Language is an interesting thing. In Britain a fag is a cigarette. In the States it's a homosexual.
Sucking on a fag in England means something far different than sucking on a fag in America.
In the States we haul freight in a truck or a big rig. In England it's hauled in a lorry.
If someone asks you if you want to shag, what comes to mind? If you're an American it's a dance. If you're English it means getting nekked and doing the horizontal mamba.
Yep, I'm bored as hell and thinking of silly shit.
So, what terms or phrases can you think of that mean something completely different in places other than your own?
