I think what makes this young woman a Super Freak to Rick is that she likes having sex. I don't think that's fair. The tendency to call a woman who likes to have sex a freak allows for stigmatizing her, and thereby gives one permission to treat her badly. If she should ever accuse you of rape, you could always say, "well, she's a freak." A person who is not normal. Not part of the community. This stigmatizes female sexuality, regardless of its freakiness.
