虽然有些人利用鸡蛋护肤美容，但没人希望被外人看到脸上流着鸡蛋的样子。成语“have egg on your face 脸上有鸡蛋”的实际含义是形容一个人处在尴尬、狼狈不堪的情况中。我们也可以说 be left with egg on your face，意思是一样的。注意这两个表达都是非正式的口语表达。

例句

I was left with egg on my face when the lecturer discovered I had copied parts of my essay from the internet.

The company was left with egg on its face when their latest software was found to contain a virus.

I don't want to end up with egg on my face so I'm going to prepare thoroughly for the presentation.

请注意

”Teach your grandmother to suck eggs 教你的祖母怎么吃鸡蛋”这个表达的实际意思是班门弄斧，在行家面前不自量力、卖弄本领。

例句
