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
