African-American culture... it's kind of a dodgy thing for me to be talking about, as a white Brit, I guess, so you should maybe take what I say with a pinch of salt, but...
I think it sort of blurs the line between an American subculture and an actual nationality, a bit. It's not a nationality, but it has some of the characteristics of one: shared cultural history (albeit one of slavery and segregation), certain linguistic similarities, different trends in music, art, literature, etc., they had a fairly strong nationalist movement at one point which garnered a reasonable amount of support (unlike white nationalism, which has never really been more than a fringe thing in the US)... you get the picture. It doesn't necessarily exclude all non-black people or include all African-Americans, either; it's a vague cultural/subcultural grouping. Some people take great pride in it, some people don't care about it very much.
What bothered me was that it sounded as though you were picking out a bad comedy film as representative of African-American culture, which as Carciofus said, is kinda like picking out weird porn as representative of Japanese culture. But it doesn't sound like that's what you were doing, so never mind.
And African-American culture is the original source of rock music, but it doesn't include all rock music. Viking folk metal, probably not.
