EATING CROW IS A COLLOQUIAL IDIOM, USED IN SOME ENGLISH-SPEAKING COUNTRIES, THAT MEANS HUMILIATION BY ADMITTING HAVING BEEN PROVEN WRONG AFTER TAKING A STRONG POSITION. THE CROW IS A CARRION-EATER THAT IS PRESUMABLY REPULSIVE TO EAT IN THE SAME WAY THAT BEING PROVEN WRONG MIGHT BE EMOTIONALLY HARD TO SWALLOW.
