Cách sử dụng
The expression "sour grapes" is used to describe a situation where someone is criticizing or dismissing something that they wanted but couldn't have. For example, if someone says "I don't even like that job anyway" after being turned down for a job, they are exhibiting "sour grapes" behavior. It comes from a popular fable where a fox couldn't reach grapes, and when he couldn't have them, he scorned them as sour. It is often used when someone is trying to make themselves feel better about not getting something they wanted.
