selectively permeable membrane

A hot girl's vagina.
Very selective on who's dick is permitted through the membrane (her pussy lips.)
Will often deny nervous, non-jock types. The membrane judges largely on physical appearance, not on the pretense of a good personality or wit.

Guy 1- So did you sleep with Elena in the end?
Guy 2- No, she had a selectively permeable membrane.
Guy 1- ... So she turned you down?
Guy 2- Yeah.
Guy 1- Well just say that then!
Guy 2- I needed to make an example for a definition for urban dictionary, okay?!
Guy 1- Oh, right... Wait a minute, am I on TV?!

Premeditated Wanking

Engaging in the act of wanking having pre-planned the desired time, location, and length of time in which the act of wanking should occur. Often used by homosexual men who have other, gayer things they could be doing.

"I prefer premeditated wanking over other types of wanking, I need the time to get ready for something so emotionally affectional"
