我們有句古語，說“有朋自遠方來，不亦樂乎？”可是，有朋友到訪并不見得任何時候都是讓人高興的。在你有急事要處理或者著急出門的時候，朋友意外到訪就有可能是“不亦悲乎”了。

Social terrorism means when someone you know comes to visit unexpectedly and inconveniently, often staying for a long time, and you can't tell them to leave without being rude.

Social terrorism（譯為“不速之客”或“社交炸彈”）指有熟人在你不太方便的時候突然到訪，而且停留很長時間，你又不能很粗魯地要求人家離開。

For example:

Yesterday, I was just about to go out, and then the doorbell rang. It was Sally, and she invited herself in and stayed for an hour! It was social terrorism!

昨天，我正要出門的時候，門鈴響了。原來是莎莉，她也不客氣就進了屋還待了一個小時！簡直就是個不速之客！
