A pass route commonly used by running backs (sometimes also tight ends). In this pattern, the back runs straight to the left or right, staying behind the line of scrimmage, all while looking over his shoulder to the quarterback. This is a common method pocket-style (immobile) quarterbacks use to "dump off" the ball to the back when they are under pressure from the defensive rush. It is usually a safe pass, but if the receiving back is behind the quarterback when the ball is thrown and he does not catch it, the pass counts as a fumble.
