first recorded 17th c.

Coined by William Shakespeare in 1611, the term appears in his play *The Winter's Tale* as a description of a woman's temperament. The playwright’s use of the phrase established the specific comparison between a lack of human warmth and the temperature of a fish, though the social inconvenience of such a personality has since outlived the context of the scene.
