Nobody says "Dang" in the UK - that always smacks of American false prudishness, a bit like your daft refusal to describe public toilets (i.e those not in the home) as the toilet or lavatory, and instead call it the 'bathroom' or 'rest room' -even though there's nowhere to take a bath or have a rest!

Very strange, bearing in mind that USA-Ian's seem to pride themselves on their straight-talking, no bullshit manner! :-)
