Back on topic... (I think this topic has mostly derailed itself from the... second post...)
The word, from my experience, means uneducated "African American" person. And I say african american because I don't want to throw the word black in (because that can account for more people than standard americans of dark skin, and thus fall out of American social lexicon.) I'm interested in how the word is viewed outside of America, if it's used at all (I highly doubt it.)
I'm mulatto, but with dark skin (unlike my brother and sister) and we live in a mostly white-suburban neighborhood. Our family is pretty much mixed across the board anyway. We don't use that word, but I know when I'm out with my friends (my white friends) in college and we're telling jokes the term will come up, and it doesn't bother me because it isn't a threatening context.
I spent the weekend at an ex-girlfriend's house once. Her father's extremely racist, they live in a very very very small community in Georgia, and he once joked about wearing a white sheet over his head and jumping out at me. Didn't bother me, because of the context.
Words by themselves truly don't have any power. I think anyone with intelligence will understand that. Moreso, it's when you understand the way in which words can be used that you flirt with the true nature of words. It's not the words themselves, but the culture that defines them. We give them power, and if you can't see past their superficial nature, then they can be used against you, and usually are.
Back on topic again, while I or anyone I know might not use the word directly to mean uneducated african american's, the nature of the word, and sometimes the word itself is implied in conversations I've had or heard others talk about. I remember at a job interview my step-mother had, the person giving the review was surprised my mother didn't talk "street." He used a soft version of the word, but it's intentions were implied. And indeed, there is a certain level of calmness you may feel when that person sitting next to you all tense suddenly realizes that no, you aren't going to mug them or whatever. Sad as it may be.
I think people are generally smart enough to know the double-meanings behind words that are said. If someone wants to use the word to hurt someone it's very obvious. Furthermore I feel that there'd be no other reason to use the word other than to cause confusion. There's really no way to deal with the issue and step around it because ultimately, the way the word is veiwed and expressed is up to the people as a whole, and not a singular entity.
To answer soavifox's question, yes, the term is used to denote uneducated blacks in america, and I see no problem with that. In my family and community (well, the black people I know in my community) use the term "negroes" or "black folk", but the idea is the same. It's a way to say the word and save clemency.
