The earliest recorded use of the term “shootout”—defined by the Oxford English Dictionary as “a sustained exchange of shooting, a gun-fight”—comes from a 1953 New York Times article, which refers to a “justly famous shoot-out between the Earps and the Clantons in the O-K Corral.”

Merriam-Webster doesn’t invoke that famous 1881 gun battle in Tombstone, Ariz., in its definition of “shootout,” which it renders “a battle fought with handguns or rifles.”
