as far as using the words bitch, slut, hoe, whore-its apart of the lifestyle that these rappers are promoting, yes, the words have definition, but if the word is used in repeated context and conversation, then people become used to the word and its usage. Remember, all of rap songs being played are nothing more than a person pushing that type of lifestyle, which is very hard to pull off. It represents an idealized fantasy world where normal people can't reach. Thats the reason why people like this music, it represents a higher state of economy with which most people cannot reach. This is the reason why guys like it, here again-what normal straight guy wouldn't like to have money, women and sex. Its nothing more than a lifestyle and most people don't use it in their normal speech. Here again, my mother would slap me if I called her a bitch, however, if I did it on a normal basis, she would get used to it though it may cause more psychological damage than normal. As far as the term nympho goes. That word has been twisted by the sex industry. Nymphomania is a psychological disorder in which a woman is obsessed with sex, she cannot get enough. Calling a woman a nymphomanic means that she psychologically enjoys sex to an excess. This term is a layman's term for it, the clinical term is hypersexuality. As far as the term pornography goes, that is open for debate, mainly because of the words determined to be obscene, just what is obscene in a person's mind, one person's obscenity is anothers pleasure. As far as the women who appear in these videos, they are professional dancers, just like the back-up dancers for Brittany Spears or any other music star, they are professionals, they get paid to dance around, and every person when making the video is very professional, the women don't see it as them being degraded, they see it as a paycheck. It is wrong to say that these women enjoy being degraded because they are not in fact being degraded, noraml people who watch these videos assume that this is real life, this is how they should act and they act accordingly, but hey whatever sells the most records.
An interesting point to make, maybe the reason why women are called nymphos is because the thought of a woman having more sex drive than a man may cause the man to become defensive and use the term to make is ego feel better saying its the woman who is abnormal
