A term for when you have not ever french-kissed someone, evolving from virgin, but the 'sn' meaning 'snog' which is english slang for 'snog' also meaning french kiss.
"Have you ever kissed anyone?"
"Ha, you're a snirgin!"
One who has never been banned on a message board. Its origin is the convergence of the term s/n (sign in name) and virgin.
The moderators never bother me. I'm still a snirgin.
