the act of having sex doggie-style & pulling out (seemingly accidentally) @ which point you allow another male to take over, unknown to the recipient. At this point the first male sneaks out & reappears to the recipient, preferably by waving through a window from the outside.
When your getting a girl from behind and you let your friend take your place without her knowing, you run outside and knock onthe window and wave to her yelling Wahlah!
Have sex with your girl in the "doggy style" position in front of a window. On the "out stroke" pull completely out and have a friend (or if your from the south, a relative) fill in for you. Hopefully she will never realize the switch. At this point, run outside to the window, stand in front of it and wave at your girl while she is still getting nailed by who she thinks is you.
The act of releasing a turd that is so thick and long that, upon cut/release/splashdown, you not only obtain a sensation of levitating, but you experience a chill, followed by a brief look behind you in disbelief and extreme exhaustion/weakness.
This experience, in it's entirety, has been known to mimic the sensations experienced by street magician David Blaine while performing his world-renowned levitation during the airing of "David Blaine: Street Magic"
