Hoverboarding

A sexual position where the person on the bottom is lifted and carried in between the legs of the person on top by ropes. The person on top puts his dick in the bottom's butt and walks around while doing this and pretends to be Marty McFly.

Guy1: Me and my girl tried hoverboarding last night. It was the best sex we have ever had.
Guy2: Whatever you say, Marty.
