take the edge off one's anger

If something takes the edge off a situation, usually an unpleasant one, it weakens its effect or intensity.

如果你做某个事情能够take the edge off 某个情况，通常这个情况是一个不太好的情况，那么就是说它可以减轻或者削弱(不良事物的影响) 。

所以如果我们说消消气，其实就是减轻你的脾气造成的影响(坏脾气)，就可以说成take the edge off one's anger，比如

His apology took the edge off her anger.

他道了歉，她的火气就消了些。

还有一些其它情况也适用于这个短语，

We won't be having lunch for another hour, but if you're hungry now, I've got some snacks to take the edge off.

我们还有一个小时才吃午饭，但如果你现在饿了，我有一些零食可以抗一下饿。
