1. Au fait – this is an example of a French expression that has become part of the English Language. It means to have good detailed knowledge of something. (This is not slang but a very British English expression.)

Au fait是英語從法語中借用的表達之一。它的意思是對某事物有非常細致的了解。（它不是俚語卻是非常地道的英式表達）

2. Blinding – if something is blinding, it means that it’s excellent.

如果某事物是亮瞎眼的，意思就是這個事物非常棒、非常出色。

3. Bugger all – if you’ve got bugger all for dinner, it means you have nothing. (This is an impolite expression so use it with caution)

如果你說晚餐吃個屁，那就是說你什么也沒有吃。（這種表達十分不禮貌，需慎用）

4. Cock up – This can be used as a verb or a noun and it means to make a serious mistake or a mistake. (It has nothing to do with male parts!)

這個短語既可用作動詞也可用作名詞，它的意思是犯了很嚴重的錯誤(動詞)或錯誤（名詞）。（這個表達跟男性器官毫無關系。）

5. Donkeys’ years – a long time or ages

很久很久，好多年

6. Gobsmacked - “Gob” is mouth in British English and if you smack it, you probably would do it because you are amazed or shocked.

Gob在英式英語里是嘴巴的意思，如果你咂嘴，可能是因為你感到驚訝或震驚。

7. Gormless – another way to say vacant or clueless.

表示茫然或無知愚蠢的另一種方式。

8. Gutted – really upset.

非常失望的

9. Hunky-dory – fine, going well

很好，進展順利

10. Knackered – very tired, exhausted

非常累，精疲力竭

11. Lurgy – if you’ve got the lurgy, it means you are ill with the flu or other mild disease.

如果你身體小恙，也就是得了流感或其他小病。

例句：

12. Nice one! – If someone is impressed by what you’ve done, they could use this expression. It’s similar to “good job” in American English. It can also be used sarcastically.

如果一個人對你所做的事情印象深刻，就可以使用這個表達。它跟美式英語里的good job差不多，也可以用于帶有諷刺意味的夸獎。
