There's the opposite problem too, where "fanny" has a different meaning in the UK vs. USA. There's the classic line from "The Office" about it ("over there fanny means your arse. Not your... minge") and I think most folk are pretty aware of the American meaning here these days.

I wonder, is it too much to ask that we (as in, the various English speaking places) understand the different meanings of words that are offensive in one dialect but have a different and mundane meaning in another dialect?
