I guess I should be offended, but for some reason I'm not? I'm speaking only for myself here, but it's almost like the intent behind the usage matters to me, and listening to the song, I got the feeling that she's purposely trying to paint outside the accepted lines of society in all regards. I'm glad the song exists, just like I'm glad the song "Sexy MF" by Prince exists. I don't necessarily like either of them, but I recognize that art is sometimes supposed to be provocative.
