As a man reaches climax whilst in the "doggie style" position, the man pulls out and spits on their partner's back, fooling them into thinking that he has ejaculated, however, when their partner turns around, the man lets loose his baby yoghurt in his partner's face.

Houdini - (noun) An individual who pulls a disappearing act. (adj.) The act of "disappearing."

ok, the real definition is this: You are doing a girl doggy style whilst she if facing a window to the outdoors...half way thru your thrusting, you do a pull out move (to say finger her a little...) but then your friend who is strategically hidden in the room sneaks in and inserts himself as if it were you....this is when you quietly exit the room, reappearing outside the window when you now (smiling ear to ear) wave at your girl, who comes to the realization that, "if you he is out there, who is fucking me!!!?"....hillarity ensues

After doing a girl doggie style or anal. You pull out and spit on her back right before you're about to blow your load and when she turns around thinking you're done you shoot your load in her face.

Is a woman that possesses the proper fellatio skills that allow her to fully throat your dick all the way down to your nuts, therefore making it completely disappear. Once in a blue moon you may come across a houdini that can even manage to make your balls disappear as well and if so, wife her quickly.
