What is a, "one-timer" in ice hockey?
Ice hockey is a sport typically played with one goalie and five skaters on each of two opposing teams.  A one-timer is an expression used to describe a shot taken by a player directly from a pass of another player in a single motion.  This does not necessarily have to be a shot on goal, but a one-timer is so named to describe the backswing and striking of the puck from a pass, deflection or re-direction without stopping or accepting the puck first.  The idea behind the name one-timer refers to the idea the shooter has one opportunity to make contact with the puck in this manner and without proper time is at risk of missing the shot entirely due to the puck being in motion as the shot is attempted.
