A complex sexual maneuver, involving a Filipino duck, a loaded asshole, and one drunk bitch.
The move is begun when the bill of the duck is shoved into the loaded asshole (which can be possessed by anyone in the party). When the duck opens its bill to quack, the shit must then be planted inside the open mouth. The duck's bill must then be removed from the asshole and stuffed into the previously lubricated vagina. The duck will then proceed to deposit the shit into the vagina, thus space docking the girl.
Other variations include the Mississippi Mallard Docker.
