I don't live in America either, but I went on a cruise once and there were many Americans, including a black American couple who were very obviously urban. By which I mean, the wife wore high heels and a tight jeweled mini-skirt on a sea-kayaking excursion...clearly signalling that she hadn't spent much time outside of a city.

Anyway, I was shocked when they spoke exactly like The Jeffersons, with all the exaggerated whooping, non-stop vernacular, and stage-like mannerisms. It was so over-the-top that I honestly thought they were play acting, but after chatting with them for a while I realized that was just how they were. They were very nice people and clearly having a great time.
