I'm afraid he's spot on. The term for a chick that is into dudes that are 'pro' (in skiing) is simply a pro-ho.
HOwever, personally I reject the idea of females as 'hoes'. I think this is mega sexist and absolute crap. If you're a chick thats into skiing, and as such you happen to like ski dudes then you're just a chick enjoying skiing nothing more to be said.
There's nothing different from the little boys popping a boner over a myriad of attractive ski pro chicks.
