X is a fictional gun-fighting martial art discipline that is a significant part of the film Y. It is based upon the premise that, given the positions of the participants in a gun battle, the trajectories of fire are statistically predictable. By pure memorization of the positions, one can fire at the most likely location of an enemy without aiming at him in the traditional sense of pointing a gun at a specific target. By the same token, the trajectories of incoming fire are also statistically predictable, so by assuming the appropriate stance, one can keep one's body clear of the most likely way of enemy bullets

Give me X and Y
