如果老外或者有人跟你说“Are you smoking”，可要当心了，这可不是问你抽不抽烟，而是暗暗在“怼”你！
从字面意思看，“Are you smoking”表示你正在抽烟吗？但在口语中，它其实是说人傻，可以翻译为：你是不是傻？或者你脑子进水了吗？以前经常用smoking来指代吸毒，人们会开玩笑说你脑袋吸傻了吧，“Are you smoking”后来就引申为“你是不是傻？”
Are you smoking? 你是不是傻？你脑子进水了吗？
Are you smoking? You were cheated by him several times.
你是不是傻？你被他骗了多少次了。
What are you thinking? Are you smoking?
你在想什么？脑子进水了吗？
What are you smoking? I don't have any classes that early.
你这是什么意思？这么早我哪有课？
A: China has 10,000 people.
B: You must be smoking!
A：中国的人口数是一万。
B：你一定是傻了。
除了stupid和fool，英语中还有很多说人傻的表达。
dope [doʊp] n.笨蛋；麻醉药物；涂料

coo-coo/cuckoo [ˈkʊkuː]
cuckoo就是布谷鸟，这种鸟会生蛋，但不会孵化，所以它们会把蛋下到别人的窝里。后来cuckoo就有了说人笨的意思。

那么，你抽烟吗用英语怎么说呢？询问别人是否抽烟，正确的表达是：
Do you smoke? / Are you a smoker? 你抽烟吗？
注意，不要用can，因为会有一种质疑的语气，有点不太礼貌。
Do you smoke? No, I stop smoking for the sake of health since last year.
你抽烟吗？从去年开始，我就已经戒烟了。
