a baffling term used to indicate unavailability, although the nature or owner of said pocket remains unknown; perhaps developed through mistaken conflation of ‘out of town’ with the standard phrase ‘out of pocket,’ which indicates expenses borne personally; in a business context the propensity to avoid simple, perfectly serviceable words like ‘unavailable’ or ‘unreachable’ that could connote a lack of team spirit has further driven usage of this term; a competing school of thought contends that this phrase has its roots in American football, when the quarterback leaves the area of protection afforded by his linesmen, though there is scant evidence to support this etymology 1
