eat one's heart out
Definition from Wiktionary, the free dictionary
Disputed. Three schools of thought exist:
- From "This will eat your heart out.", suggesting that the recipient of the taunt will have their heart, the core of their being, eaten out with desire, bitterness, or pain.
- From the 16th century "to eat one's own heart" (to suffer in silence from anguish or grief), possibly from the Bible "to eat one's own flesh" (to be lazy) The phrase "to eat one's heart out" appears as a formulaic phrase in the Iliad, meaning to experience extreme grief. (For instance, Iliad.24.128, many other locations.)
- When used as the taunt "Eat your heart out, [someone]!" a suggestion that the recipient of the taunt "eat up" as much as they like. (From the same construction as "dance your heart out," etc.) Literally, similar to "have all you can eat!" Figuratively more akin to "experience me besting you."
- (idiomatic) To feel overwhelming sorrow, jealousy or longing, to grieve.
- The Germans are eating their hearts out over their defeat against Spain in European championship games for football.
- Eat your heart out, pal! We won the title!
