33 percenter
A female that claims to be a virgin, yet only 33% of her relevant orifices remain pure. How special can it feel to be the first through the front door when the entire football team has been through the back door and explored the chimney already?
"She says she's a virgin but she's totally a 33 percenter. Just ask her about when she blew Scronaldo under the bleachers, or when she let your boy ZK, Alpengeist, Booms, and Brandopolis put it in the back door!"
