Hell hath no fury like a woman scorned

Meaning: A woman rejected in love can be very angry and dangerous.

Note: hell (noun): (according to various religions) a place of suffering where bad people go after death | hath (verb): [old English] has | fury (noun): violent anger; (Fury) in Greek mythology a female spirit of punishment | scorn (verb): to reject contemptuously

Origin: This saying is based on lines from The Mourning Bride by William Congreve (1670-1729):

Heaven has no rage like love to hatred turned,
Nor hell a fury like a woman scorned.
