I think some girls/women wear the slut label with a certain degree of pride. This is not a facetious comment, simply an observation of changing times. Think about it ... there was a time when any woman would have shuddered at the thought of being considered a "slut". Nowadays, women openly admit to (a)being, (b) being referred to, and (c) being thought of as a slut. It's simply not the earth-shattering event it used to be (i.e. one's reputation could be ruined, hence ending a woman's slightest hope of marrying well or advancing professionally, etc.).

Gypsy's comment is a case-in-point. "Depending on the culture or religion I myself am a slut ..." I think where only negative connotations used to be attached to sexual promiscuousnous amongst women, today women wear the sexual hat much more comfortably. Western females commonly refer affectionately to each other using terms that were formerly considered offensive. For example, "you're such a slut!", "you're such a biA**tch", "aren't you the cougar?", etc. Women now also refer to each other as female "players".

In Western culture at least, these words, while still considered offensive to some, no longer carry with them quite the stigma they once did. The meaning of the labels has evolved in such a way that while the words may still be used in an offensive manner (i.e. to convey an insult), they may also be used affectionately or as a badge of honor of sorts. It's much cooler now to be a bad girl and flaunt it than it was years ago. Changing times and trends, no more no less.
