The ～と言わんばかりに grammar point is used to express that someone's action or behavior is so strong that it's as if they are saying something without actually saying it. It can be translated as 'as if to say' or 'almost as though stating' in English. This form is often used when the speaker wants to express a strong speculation about someone's unvoiced thoughts or feelings based on their behavior.
