Explanation

  • To become extremely angry, suddenly and intensely.

Origin

  • The phrase possibly originates from the sport of bullfighting, where a red cape (muleta) is used to provoke the bull, making it charge in anger.
  • Another theory links it to the physiological response of anger, where blood rushes to the face, potentially causing a flushed (red) appearance or even affecting vision in extreme rage ('red mist').
  • The expression dates back to the early 20th century.

Alternatives

Situational Appropriateness

Misunderstanding Warnings

Examples

  • Don't mention her ex-boyfriend; she just sees red.
  • I try to stay calm, but incompetence makes me see red.
