身體上的那個開口
這一支就是核心畫面本身，還沒有被丟到別的東西上。
noun · B2
A rude word for the opening at the end of the bowel, in a person or an animal, where waste leaves the body. The ordinary medical word for it is anus.
屁眼（粗話）
核心畫面
One way to hold this word: it names the hole at the very bottom of the body, the least part there is. Everything else it does is that same picture pointed somewhere new — at a person you have no respect left for, or at a place you would not want to spend an afternoon. Because the picture itself is dirty, the word stays heavy wherever it goes; the source marks it taboo and vulgar in every use.

可以想成：這個字先是身體最底下、最不體面的那個開口。它其他的用法，都像是把同一個畫面丟到別的東西上——丟到一個你已經完全看不起的人身上，或丟到一個爛透了的地方。因為畫面本身就很髒，所以這個字走到哪裡語氣都很重。辭典在每個用法上都標了 taboo 或 vulgar，不是只有罵人的時候才算髒話。From the word’s history
The word is arse plus hole, written arce-hoole in Middle English; Old English had ears-þyrel, literally the same two parts. So the body meaning is where the word starts, and both of the other uses are that image aimed at something new.
這個字就是 arse（屁股）加 hole（洞），中古英語寫成 arce-hoole；古英語的 ears-þyrel 字面也一樣。所以身體的意思是起點，罵人和罵地方都是把那個畫面搬過去用。

把那個畫面丟到人或地方上
同一個畫面，換了對象：不再指身體，而是指一個人或一個地方在你眼中的位置——最底層、最不值得尊重的那一格。

A very rude word for a person who treats other people badly — someone mean, selfish, or too stupid to care about the trouble they cause. It is a swear word and it insults the person it is aimed at.
