明明是在给女朋友写肉麻情书，结果却不小心发到了全公司同事的邮箱里，这个时候你会是什么反应？Oh，no！项目文案还有最后一页就写好了，结果按错一个键，整个文档都不见了，什么反应？Oh，no！对啊，这样的时候在英语里就是叫做ohnosecond，挺贴切的吧？

An ohnosecond is that very short moment in time during which you realize that you have pressed the wrong key and deleted hours, days, or weeks of work.

Ohnosecond，暂译为“糟糕一秒”，指你意识到自己按错键把几个小时、几天，甚至几周的工作成果都给删掉的那一刻。

In a broader sense, it may also refer to that minuscule¹ fraction of time it takes your brain to realize that you've just made a GIGANTIC mistake and reconcile the fact that it is too late.

从更广义的角度来说，“糟糕一秒”可以指你的大脑意识到你刚刚犯了个非常严重而且无法挽回的错误时的那个瞬间。

仔细看一下这个词，其实就是“oh no second”三个词一起构成的，大概是因为英语国家的人们在做错事情的时候通常都会脱口而出“Oh no！”这个感叹句吧。

For example:

Dave sent his girlfriend pictures of himself with another woman, by accident, regretting it an ohnosecond later.

戴夫不小心把他跟另一个女人的照片发给了他女朋友，他意识到以后后悔不已。
