In English, when we say someone has to ’eat humble pie’, we mean they have to admit they can’t do something they boasted about.It’s a bit humiliating for them。 承认错误

We say "eat humble pie," although this expression isn't used very much anymore. You "eat humble pie" after you have made a claim or bragged about something that didn't come true. For example, if I said I was going to win a contest, but then got last place instead, you could say that after the contest I "ate humble pie" and accepted my last place finish.

To be forced to. Apologies or to admit a fault.

As Zach stated, it's not used much.

To suffer humiliation / to accept that you are wrong and have to apologize or accept you are wrong regarding something
