People use it as a slightly unkind name, often while teasing: “Don’t be such a killjoy.” It is not a swear word, but it is not a kind word either. You might call someone a killjoy for a small thing, like turning the music off, or for a bigger one, like shutting down a whole celebration.

People use it as a slightly unkind name大家會用它當一個有點不客氣的稱呼，often while teasing常常是半開玩笑地說："Don't be such a killjoy"『別這麼掃興嘛』。It is not a swear word它不是髒話，but it is not a kind word either但也不是一個友善的字。for a small thing為了一件小事, like turning the music off像把音樂關掉，or for a bigger one或為了比較大的事, like shutting down a whole celebration像搞砸整場慶祝，you might call someone a killjoy你就可能叫某人killjoy。

Though actually, the person getting that name may only be trying to be careful, fair, or quiet; the word shows how the others feel in that moment, not the whole truth about that person.

Though actually不過其實，the person getting that name被這樣叫的人 may only be trying to be careful, fair, or quiet也許只是想小心一點、公平一點，或安靜一點；the word shows how the others feel in that moment這個字只是表現出當下其他人的感受，not the whole truth about that person不是那個人的全部真相。
