Language always changes, and some who know these things tell us that some American words are actually old English ones, like garbage & faucet.
Friends tell me that I use American turns of phrase, which I think I've always used - but I grew up near a USAF base.
Although I deeply dislike 'passing' and don't use it, I am not sure its use can be laid solely at the door of the US - I have most frequently heard it used by Irish people. But then a lot of expressions are used by both Irish and Americans.
If you don't like an expression, don't use it.
