"Bite your lip" is an expression meaning to hold in your emotions or restrain yourself from speaking out or reacting. It can be used in situations where you feel angry or upset, but you decide not to show it. For example, if someone says something rude to you but you don't want to start an argument, you might "bite your lip" and stay quiet. It's like trying to control how you feel by clenching your teeth and not speaking.
