Your fucking the bitch from behind and your really gettint into it, your slapping that ass, pulling that sluts hair and all of a sudden BAMMM you spit right on her lower back, so she thinks you cumed so she turned around with a big smile and FUCKING BAMMMM you punch that bitch in the face and cum all over her face, bammmm she thinks you cummed on her back but u faked her out the houuuudinniee whaaaaaaaaat

When you make two fingers disappear inside a woman's anus, while mistaking it as her vagina.

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.

a houdini can also refer to a sex act where a male, who is fucking a chick doggy style in front of a first floor window, quickly pulls out, and his friend jumps in to continue banging her. the first man then proceeds to run naked and dance in front of his bitch outside the window. magic, eh?

nonetheless, the more accepted defineition is the genuine spit and skeet technique.
