Q
- quarterback
- American football: One who directs or leads; a mastermind; also used as a verb, to quarterback. It is also used as a term for a supporter or critic of a football team or game, and by extension, an uninvolved observer who criticizes or second-guesses; see Monday morning quarterback, above. In American football, the quarterback is the player on the field responsible for coordinating and directing play, and the one to whom the ball is snapped at the beginning of each play. OED cites figurative use of "leader" to 1961; it dates the verb usage to 1952, a cite which in itself cites the term to 1945.
