Get the the houdini mug.
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.

A sexual position/plot where a man fucks a woman from behind facing a window. At this point his friend secretly takes over for him. The man walks outside and looks into the window and waves. The woman will be suprised/shocked to see him outside and wonder who is fucking her instead

When a man is close to climax while having sex in the doggy style position he spits on the womans back thus giving her the sensation that he has ejaculated. When she turns around the man gives her an unexpected facial while shouting "Houdini"!
"My girl would never let me give her facial so I had to give her a Houdini"

1: A poop that mysteriously disappears when you stand up to flush.

2: Having to poop but managing to squeeze a fart around it. Thus defying the laws of poop gravity.
Example 1:
I'm telling you... I got up to flush and the 2 hour terd was gone. Total Houdini.

Example 2:
I thought I was going to shart for a minute there but I Houdinied it.

when you're fucking a girl from behind, you pull out and spit on her making her think you blew your load on her back. when she turns around you blast it in her face and say "how do you like that magic trick bitch!"
