Cách sử dụng
The word 'smug' is used to describe someone who is very pleased with themselves, sometimes in a way that annoys others because they seem to think they are better than everyone else. It is important to use this word cautiously and in appropriate situations, as it can be seen as rude or insulting. For example, if you see someone boasting about their achievements and making others feel inferior, you could describe them as smug. However, it is best to avoid using this word in polite conversation or when describing someone's positive traits or actions.
