A word degenerate men often use to describe other males who don't have massive amounts of random sex with women they just met (only women because these same men often take part in gay bashing and have no concept on female biology and pregnancy.) Macho or fragile men with AIDS, other STD's, prison time, or children they never see often use this word against smart people to make themselves feel better.
Mark is such a virgin, he hasn't had a girlfriend in two years now.
