A sexual move. With both bodies perpendicular to each other, the top's only point of contact is the groin/butt of the other person, and you raise your feet/head so your body's at an obtuse angle. The top person then starts to rock to make a grinding effect. Not as effective as 69.

Mike: "There are other numbers you know"
Johnny: "Yeah, well if I say we 53ed, we'd sound pathetic"
