hudini

While giving it to a girl from behind, spit on the arch of her back and moan as if you have completed, when she turns to thank you, blow your load in her face and yell, "Abra Kadabra Bitch!!!" or some other magic word, to give it the hudini effect

Theres another definition to this one which has not yet been said.
It is when a dude is fuckin some girl doggy style.
Then switches with a friend.
Then runs out the window and waves to the girl.

doing a girl from behind, spitting on her lower back, making the oh sound, then when she turns around, nut on her face (some prefer the hudini-zombie combo)

a.k.a. "sneaky steve"

a sexual remover where the male is getting a feamle from the back. while doing this he pulls out and spits on her back. when the female turns around he busts in her eyes and all over her face.

to fuck a girl, spit on her back to maker her think you blew your load, and when she turns around, bust your nut in her face.

OK so this is how it goes, you fuck her from behind spit on her back to make her think you blew the load, then when she turns around you shot it in her face, you appologize to her and tell her you'll get a towell, but instead you just haul ass outta there.

while fucking a girl doggie style, pull out and spit a large amount of saliva on her back to make her think you finished; if done right she will turn around and you can bust all over her pretty face. (this technique works best on blondes.)
