Eating crow
You get forced to swallow your pride like a gross piece of roadkill because you were wrong.
My brother ate crow when he said my new car was a piece of junk, and it turned out to be the best car ever.
My teacher had to eat crow when she said I'd never pass the test, and I aced it.
My friend ate crow when he said my haircut was the worst, and now everyone says it's the best.
