Surprise Moosey 

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"

While doing a woman in the doggystyle position you must position her so she is facing the closet. Upon a predefined signal your friend jumps out of the closet and takes a picture as you put your hands up to the sides of her head with your fingers splayed. your friend then runs off and posts the photo in as many places as possible.

I have a pic of stephanie as the surprised moose when she whored out to me last night!!!
