Cách sử dụng
The expression "give somebody a dirty look" means to look at someone in a way that shows dislike, anger or disapproval. You might use this expression if someone is doing something that you don't agree with or something that frustrates you. For example, if someone cuts in front of you in line, you might give them a dirty look to show your disapproval. It's not always the nicest thing to do, but sometimes it can be a way to communicate your feelings without saying anything.
