A Virginator is a guy with a special interest for girl's who still are virgins. His only goal is to sleep with a girl who still has her hymen intact.
John: Damn, that chick is fine!
Rob: Seriously, she's probably like 16.
John: I like them young and fit...
Rob: Man, your such a Virginator.
Woho! That girl last Saturday was the third virgin I've had this year. They should call me the Virginator.
