When you are thrusting violently in the "doggy style" position and the penis slips out of the vagina and into the anus, forcing the femal to crawl up the wall.

 Get the the geckomug.
Get the the geckomug. 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.
Then you hit the floor.
Sam: "time to get geckoing"

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."

 Get the geckoingmug.
Get the geckoingmug. The act where a dominant male performs an upward reptilian shuffle on a submissive female, climbing until he can get his salamander firmly anchored in the throat of his victim.
I didn't think she was going to perform fellatio of her own accord, so i unleashed 'the gecko' and started to climb. I made the summit and achieved maximum suction.

 Get the The Geckomug.
Get the The Geckomug. The gecko is a sexual act between two people or more (if that’s what your into) where the thumb is inserted into the anus of the other player and that person is made to climb up a wall in the motion of the cold blooded reptile known as a gecko.
Hey guys, the coolest thing happened! Me and my dog did the gecko last night!!! He claimed sooo far up the wall!
