behind the eight ball

In a bad situation, bad luck. The term, originating in the United States in the first half of the 1900s, comes from a form of pool in which all the balls (which are numbered) must be pocketed in a cer- tain order. The only exception is the No. 8 ball, which is black. If another player touches the eight ball he or she is penalized. Therefore, if the eight ball is in front of the ball one is trying to pocket, one is in a difficult position.
