英文释义：
To face the repercussion of being incorrect after one's claim, boast, or assertion is refuted; to eat one's words.
在主张、吹嘘或断言被驳斥后，面对不正确的后果；承认说错话
You'll be eating your shirt if this new engine isn't as fast as you say it is.
如果这台新引擎没有你说的那么快，你就得收回自己的话。
中间的 one's 可以替换成各种所属格，比如：my, your, his, her 等等。
eat your shirt
我们都知道，shirt 是常穿的服饰“衬衣”之意，
有的小伙伴第一反应就是，
它的意思不会是“吃你的衬衫”吧？

但实际上，eat one's shirt 有两种意思↓↓
