cheek by jowl 緊緊靠著、形影不離。

Means: Side by side; close together.
（和…）緊緊靠著，（和…）非常親昵

If you say that people or things are cheek by jowl with each other, you are indicating that they are very close to each other.

來源：這個短語最早從莎士比亞的《仲夏夜之夢》里來，當(dāng)時叫"cheek by cheek"。兩個世紀(jì)之后才出現(xiàn)了"cheek by jowl"這種說法。"Cheek"和"jowl"都是臉頰的意思。想想，兩個人的臉頰都貼到一起了，還有比這更親密的嗎？所以下次要表達(dá)和誰形影不離就可以用到了！

請看例句：

1. My house stands cheek by jowl with a department store.
我家緊靠一家百貨商店。

2. We see the union leaders cheek by jowl with the capitalists.
我們看到工會領(lǐng)導(dǎo)人和資本家們打得火熱。

3. I thought that Jenny and Leo had a fight, but I saw them today in the cinema, cheek by jowl.
我原以為Jenny和Leo吵架了，但是我今天在電影院里看見他們挺親密的。
