The phrase is borrowed from the sport of ice hockey, but now applies in many contexts.
In hockey, a crude but effective save where the puck is diverted not with the end of the curved stick but with the handle. The
player simply falls on the
ice or bats at the puck with the stick. No points for style, and often fails, but a save is a save.
In other contexts, whenever a "
player" manages to pull out a situational "save" at the last instant via reckless, feckless or
random methods. As in financial markets, when institutions manage to move the market up in the last minutes of trading thus ensuring an "up" day, even though a "down" day was in the making.
