I have a buddy who went crazy buying domain names when he heard about the pizza.com purchase, so he bought these 2 domains: queerlicious.com beernsex.com (as in beer and sex) Maybe some potential with the first one? He doesn't have any traffic going to them.
He's gonna need some beer and sex when he finds out those are reg fee. But you know what, those names are sick enough that someone will go for them. Just not me.
Reg fee means that the value of the domain is no higher that the original registration fee you'd pay for the domain at somewhere like Godaddy or another domain registrar - i.e around $5-10
TBH, I quite like beernsex.com, i'd buy it but wouldn't pay more than low $xx (around $15-$20) for it.
