The expression "what's your problem?" is a question that you ask someone when you want to know why they are upset or acting strangely. It can be used in situations where someone seems unhappy or angry, or when you are having an argument with someone and want to understand their point of view. However, it is important to note that this expression can sound confrontational or rude, so it should be used carefully and in appropriate situations.
