blooper

A blooper is a short sequence of a film or video production, usually a deleted scene, containing a mistake made by a member of the cast or crew. It also refers to an error made during a live radio or TV broadcast or news report, usually in terms of misspoken words or technical errors. The term blooper was popularized in the 1950s in a series of record albums entitled Pardon My Blooper, in which the definition of a blooper is thus given by the record series' narrator: "Unintended indiscretions before microphone and camera."
