I'm not seeking to American bash but it's my observation that they often don't have such a good knowledge of the idiosyncrasies within the language of other English speaking countries compared to how much say we british are aware of the various everyday idiomatic phrases that are unique to the americans. I think this can probably be put down to the large amount of tv and movies that are produced in the US and then get shipped across the pond.

I used the wrong word actually, didn't I , but you were very tolerant and it just about fits.

Good point you have made- not as if we don't offer them good stuff, like BBC's 'House of Cards,' which is really good but they insist on their own version. Talking about BBC miniseries, we have an American film, albeit with British actors 'Tinker Tailor Soldier Spy' okayish, but not a patch on the aforementioned- how could it be, ten times longer with Alec Guinness.
