In an all-male threesome, two men lay on their backs with their penises touching to create a "Double Boner." The third male, standing on an elevated platform positioned above the other performers, proceeds to do a backflip off of the platform. At the end of the rotation, the diver will land with the two penises engorged in his rectum successfully completing the "Double Boner Backflip."
Man 1: "Hey man, how's Kappa Alpha pledgeship at the University of Tulsa going?"

Man 2: "Well it was kind of boring until they made us do Double Boner Backflips with each other."
