near miss

noun

1. a strike by a missile that is not a direct hit but is close enough to damage the target.
2. an instance of two vehicles, aircraft, etc., narrowly avoiding a collision.
3. something that falls narrowly short of its object or of success: an interesting movie, but a near miss.

noun

1. a bomb, shell, etc, that does not exactly hit the target
2. any attempt or shot that just fails to be successful
3. an incident in which two vehicles narrowly avoid collision

A narrowly avoided mishap; also, an attempt that falls just short of success. For example, It was a near miss for that truck, since the driver had crossed the center strip into on-coming traffic, or Her horse kept having a near miss in every race, so she decided to sell it. This expression originated during World War II, when it signified a bomb exploding in the water near enough to a ship to damage its hull. Soon afterward it acquired its present meanings.
