Some websites say this expression dates back to the 18th-century England. One site says that it first meant a common facial expression used to express dislike or contempt. These days, the contempt is gone and in its place are terms like irony. An irony is when you say the opposite of what you mean, usually to be funny.

一些网站称，这种表达可以追溯到18世纪的英格兰。一家网站称，它最初是指一种用于表达不喜欢或蔑视的常见面部表情。如今，这些蔑视的意味消失了，取而代之的是反语之类的说法。反语是指说出跟本来意思相反的话，通常都很有趣。
