When you are doing a girl from behind and you are about to cum, you pull out and spit on her back so when she turns around you blow your load on her face.
THIS IS NOT THE HOUDINI - DO NOT GET IT CONFUSED.
THE HOUDINI IS WHERE YOU DO A GIRL FROM BEHIND PULL OUT AND HAVE YOUR FRIEND START DOING HER (HE WAS HIDING IN THE CLOSET) YOU GO IN FRONT OF HER, TURN ON THE LIGHTS AND YELL OUT. HOUDINI!
Oh man I was about ready so I gave her the philadelphia fakey!
