You finally decide on the perfect message to send. It’s simple, pleasant,
and in no way mentions your relationship. As you hit “send” a smile that
you haven't felt in what seems like decades pinches your lips, and suddenly
the butterflies are back.
这是我在YOUTUBE上看到的，网址如下

在影片约25秒时出现的
请问decades pinches your lips在这边是指什么意思
感谢^^

pinch的主词是a smile

a smile pinches your lips 是指什么意思?

... a smile [that you haven't felt for (what seems likedecades)]...

注意看 25 秒画面的那个smile. 你自己比较:1. 稍稍微笑2. 像画面那样大大的微笑(且嘴角要极力往两边拉开，必须像是你几十年内没这样子微笑过的程度)有没有注意到你的 lips 的情况？ 是不是因为嘴角往两边极度拉开/拉扯而感觉到/导致你的 lips 厚度变薄变紧绷？就像是用手指"pinch"你的 lips? --> ... pinches your lips

感谢楼上和前面回复的人，感谢^^
