Bite your lip.
Bite your lip.
To 'bite your lip' is to consciously decide to not say something that might be inappropriate, hurtful, or unnecessary at that moment. The physical action of biting one’s lip, which often indicates an effort to hold back words or emotions, perfectly captures the essence of this idiom. It is used in situations where silence or restraint in response is deemed wise, especially in challenging or tense situations. For instance, if someone’s remarks are irritating you in a meeting, choosing to 'bite your lip' would mean holding back your immediate thoughts or frustrations instead of vocalizing them.
