The act of fucking a chick doggy style whilst facing a window, you then proceed to pull out, and a mate takes over the ramming without her noticing.
You then race outside the house and pop up from below the window, with your hands at the side of your head, waving your fingers like moose ears and shout "Surprise Moosey!"
"Me and Dave did a surprise Moosey on Linda last night. You should have seen her face!. Worse than when I gave her a Dirty Sanchez"
