The sailor called for "straight pool", but every rack had the top ball missing. That's not like any straight pool game I've ever played.
"The psychologists call him a psychopath. They don't know what else to call him."
Don't know much about pool personally, but it's straight pool as described in the Wikipedia article of that name. Of course, that could have been written by the director of the movie for all I know.
Straight pool
To reach the point where an intragame rack becomes necessary, the balls are played until only the cue ball and one object ball remain on the table's surface. At that time, if neither the cue ball nor the fifteenth object ball remain in the rack area (or is interfering with racking in the rack area), the fourteen pocketed object balls are racked with no apex ball, and the rack is placed so that if the apex ball were in the rack, its center would rest directly over the table's foot spot. Play then continues with the cue ball shot from where it rested and the fifteenth, non-racked, object ball from where it rested prior to racking.
