The term ONE WHO CRIES FOUL can refer to three different job descriptions: UMP (3 letters), REF (3 letters), and REFEREE (7 letters). An umpire is an official in a variety of sports who is responsible for making judgments on the field, such as whether a pitch was a strike or a ball. A REFEREE is a similar official in sports, but typically has more authority than an umpire. A REF is a shortened version of the word REFEREE. All three job descriptions involve making decisions about the rules of a game and ensuring that they are followed.
