As a Scot who has spent some time in the USA on holiday lately, I have discovered a bewildering array of words which are in common use on our side of the pond and invariably mean nothing at all or something exceedingly rude on the other side.
Here’s one I didn’t know:
terrestrial television n. Any television that doesn’t come from a satellite. Americans call it just regular television, or “cable”. The distinction is a bit hazy these days, as we Brits are now fortunate enough to have cable TV as well as satellite, so we can have the rubbish pumped into us from all sorts of angles too.

Does an American-to-Canadian Dictionary exist?
