我的巴掌狠适合你那逼脸
[wŏ de bā zhăng hĕn shì hé nĭ nèi bī liăn]
This name is confrontational and provocative, implying that the speaker believes their physical strength (specifically slapping) matches or would be fitting for someone's attitude or cheekiness. 'Bitch face' is often a derogatory phrase in English too, referring to a seemingly angry or upset facial expression.
