爱思英语编者按：朋友们聊天的时候说了句特别二的话，连自己都觉得不好意思，立刻用双手把脸捂起来。看到熊孩子把家里闹得天翻地覆，无奈的爸妈只有捂脸的份儿。话说，捂脸这个动作真的很好用！

A facepalm is the physical gesture of placing one's hand flat across one's face or lowering one's face into one's hand or hands. The facepalm is a gesture which is common in many cultures, and even sometimes seen in chimpanzees!
Facepalm指的是用手捂住脸或将脸埋进手掌的肢体动作，即“捂脸”。捂脸这种动作在很多文化中都很常见，连大猩猩也会呢！

Although a facepalm is usually used to express frustration or embarrassment, in the context of a surrounding conversation it can also be used to express other emotions, such as disgust or dismay. A facepalm is often a reaction to a momentary lapse in common sense, judgement, or logical behaviour. It can be directed towards another person – i.e.: a non-verbal way of saying "I can't believe you just said/did that …" – or used in a self-deprecating way to make it clear to others that you're aware that you've said or done something stupid.
这个动作多用来表达沮丧或者尴尬，不过，在对话语境中，也可以用来表达厌恶或失望的情绪。在常识、判断或者逻辑短暂缺失的情况下，我们通常会做出捂脸的动 作。同时，这个动作也可以指向他人，即，用无声的方式表达“我真不敢相信你说了那样的话/做了那样的事，”或者用来自嘲，让别人明白，你知道自己做了傻事 或者说了傻话。
