Weavi Membrane

It is a small membrane located on the back of your neck, that enables you to breath underwater. This membrane is extremely rare. Only about 1 in 6 billion people have it. Scientist were amazed that they found the one person who had this membrane. This person has been asked to stay anonymous. If you think you might have this membrane, go and tell your doctor.

So yea...ummm, last night when I was taking a bath, something incredible happened. I slid down in the tub, to where my entire body was submerged, and I noticed that I could breath underwater. I went to my doctor the next day, and he told me I had the Weavi Membrane on the back of my neck. It allowed me to take the oxygen out of the water, just like a fish. It's quite incredible!

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?!

Paper membrane sacking (PMS)

Two females performing 69 underwater, using each other's vaginally cavity as a re-breathing apparatus.

The girls enjoyed paper membrane sacking (PMS) in the Caribbean waters more than snorkeling.
