This is done when you're "hitting
it from the back" while
she is facing a window and then
tell your girl that
you're going to grab a condom to blow in and you have
one of your close friends replace you and begin hitting
it and while
your friend is hitting
it, you run around to the front of the window and wave to her. This usually results in lots of confusion and a loss of someone close to you.
