歪果仁说Areyousmoking不是问你“抽不抽烟”，其实在骂你呢(2)

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，
后来 Are you smoking 就引申为“你是不是傻？”
可以表示对某人过去行为的困惑、烦恼或惊讶。
Are you smoking?
你是不是傻？你脑子进水了吗？

Are you smoking? I already told you not to lend money to him again.
你是不是傻啊，我早和你说过，不要再借钱给他了。
Are you smoking? You were cheated by him several times.
你是不是傻？你被他骗了多少次了。
当身边的朋友犯傻上头的时候，
你就可以用 Are you smoking 来狠狠提醒他们了...

与之类似的表达，还有：
What are you smoking?
你胡说，你什么意思，你傻啊你！
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。
