When the penis of one male slides out of the vagina and accidentally into the asshole of the other male in a mmf threesome. Most commonly occurring when one man is laying on his back with the female riding him as the other male is also on top fucking her from behind.
I was double teaming a chick with my bro when he gave me the old adirondack slide.
