n. — Hockey
a shot in hockey where a player receives a pass and instantly shoots the puck without trying to control it first; a quick, powerful redirection of the puck (see Video).
Type: 4. Culturally Significant — A one-timer is a type of hockey shot that requires great precision and perfect timing on the shooter's part since the puck is not stopped, but shot directly, usually towards the goal. One-timers cause many problems for the goaltender, who often does not have time to react (see the 2015 reference).
One-timers are partially a development to faster play commencing in the 1970s/80s. As Chart 1 shows, the term is most frequently used in Canada, with a large margin the UK and even the US.
