Get the Mallard Lipsmug. A sex move where the male is normally in the missionary position. Before completion, the male will stick a piece of lit dynamite into the woman's vaginal area, and time his load perfectly in reference to the fuse of the dynamite. This will result in the explosion of his male reproductive system into the woman's vagina, hence the term "Mallard Duck."
