Usually used to describe a post-teen ugly, unfuckable beast-like human. In women, it tends to be rare, owing to the fact that many are desperate for sex. Sadly, as sexual attractivenss of a women decreases (ie, as her body wieght increases, giant breasts not withstanding), her sex-drive increases.
Eventually it gets to a point where mostly hideous feminazis are virgins "by choice". A common nick-name for unfuckable feminazis is "Camilla" or "Camilla Gorilla", the latter describing their overall imposing nature, large girth, and general (un)
attractiveness. Virgins of this nature never laugh at love, sex, virginity or
pretty much anything. It's serious business being a virgin.
