When having sex with a woman who refuses to recieve anal sex, the man puts her up against the wall face first and proceeds to do her in the vagina from behind, but instead penetrates her anus, making her scramble up the wall like a lizard.
Woman: I refuse to do it up the pooper
Man: Ok, lets do it vertical doggystyle, face the wall
Woman: ohh ok.....aarrghhhhhh
Man to friends: haha she was like a scrambling lizard
