The term 'Houdini' is when a man is about to climax while he's in the 'doggystyle' position, he pulls out and he spits on his partner's back to try to fool them into thinking he really had an orgasm. Then when his partner turns around, the man then ejaculates into his partner's face... and ta da! It appears out of nowhere!

And that's 'Houdini' for you.
