如果某人说他要pop their head out，意思就是此人正准备快速的看一眼外面的情况。
- I‘m just going to pop my head out and check the weather to see if I need to take an umbrella with me today.
- Could you just pop your head out of the window please and see what‘s caused the traffic to stop?
值得注意的是，我们用短语 eyes pop out of your head 来描述当某人看见一个不寻常或令人惊奇的事物时目瞪口呆的表情。
- When John asked Jane to marry him and gave her a diamond ring, her eyes popped out of her head; it was completely unexpected.
