身體把氣推出去
最貼著畫面的一家：動作本身，還有那一次的結果。兩個意思之間只差在把它看成「在做的事」還是「一件東西」。
verb · B1
To let gas come out of your bottom, usually with a sound, a smell, or both.
放屁
核心畫面
Picture gas that has built up inside a body and has to come out. It arrives with a noise, or a smell, or both. Nobody planned it, nobody can take it back, and everyone in the room notices. That mix — something pushed out from inside, unwanted, and impossible to ignore — is what the word carries everywhere it goes. Point it at a machine and the machine sounds dirty and rude; point it at a person and the person sounds like something nobody wants to sit next to.

可以想成身體裡積起來的一股氣，非出來不可。它出來時帶著聲音，或味道，或兩者都有。沒有人計畫它，也收不回去，而且在場的人全都察覺得到。這個組合——從裡面被推出來、沒人想要、又沒辦法假裝沒發生——就是這個字帶著到處跑的東西。用在機器上，那台機器聽起來又髒又不客氣；用在人身上，那個人聽起來就像沒人想坐在旁邊的東西。From the word’s history
The source records a very old and unchanged word: Middle English ferten and farten, going back through Old English to Proto-Germanic and Proto-Indo-European forms with the same meaning. The noun is recorded as coming from the verb, which fits the picture: the act first, the thing second.
來源記載這是個非常老又沒變過的字：中古英文 ferten、farten，再往前經古英文到更早的日耳曼語和印歐語形式，意思一路相同。來源也寫明名詞是從動詞來的。這剛好對上畫面的順序：先有「推出來」這個動作，才有「一個屁」這個東西。
Wiktionary (kaikki extract in this packet), fart verb and noun: Middle English ferten, farten < Old English *feortan < Proto-West Germanic *fertan < Proto-Germanic *fertaną < Proto-Indo-European *perd-; 'The noun is from Middle English fert, fart, from the verb.'
Three branches
機器也在排氣
把身體的畫面借給機器。引擎、煙囪也是「把髒東西從裡面推出來」，所以借過來以後，那台機器立刻聽起來又吵又不客氣。
verb · B2
To push out smoke, fumes or gas in a dirty, noisy way — said about engines, chimneys and other machines, as if the machine had a body.
噴出（廢氣）
拿這個東西來說人
把那個沒人想靠近的東西直接安在一個人身上。罵的力道就是從畫面裡借來的：討厭、揮之不去、大家都想走開。
noun · B2
An old fart is a rude name for an older person who is seen as boring, fussy and out of touch with anything new.
老古板
