geckoing 

Jumping into a wall as high and hard as you can, but horizontally, so your position mimics that of a gecko on a wall.

Then you hit the floor.

Sam: "time to get geckoing"
*gecko*
Matt: "That was a gecko and a half"
Pete: "I've never seen a gecko with such panache!"
Ollie: "What a gecko, that was amazing."

geckoing 

Noun- to stretch the skin of the scrotum out, wrap it around your penis and masturbate with it.

I got tired of just jerking it so i tried geckoing and got off immediately.
