1. I remember that line, but not the full context....
But I thought that she meant "was the new black" in the way it's typically used in terms of fashion or pop culture. Like "strips are the new black" or "Paisley is the new black". Meaning the fashionable staple that everyone wants/has to have. I thought she meant it in terms of being a strong, assertive, aggressive woman (assuming that's what she meant by "bitch" in terms of how our society sees it) was the new in vogue thing to be.
Again, maybe I'm remembering it wrong but I don't remember it being in terms of a racial thing.
Do you have the original clip or a link to it? Now I'm curious as to just how bad my memory really is.
