‘谩骂’ is a compound verb meaning 'to hurl abusive, insulting language' — often with anger, contempt, or malice. The first character 谩 (màn) originally meant 'deceitful' or 'unfounded', and in this context conveys baseless, slanderous speech; the second character 骂 (mà) means 'to scold' or 'to curse'. Together, they emphasize verbal aggression that is both harsh and unjustified — not mere criticism, but personal, demeaning attacks intended to humiliate or degrade.

This word appears frequently in formal writing, news reports, legal contexts, and discussions about online behavior or public discourse. It carries strong negative moral weight and implies a violation of social or ethical norms. While it can describe spoken outbursts, it’s especially common when referring to written abuse — such as inflammatory comments on social media or defamatory posts — where the speaker hides behind anonymity yet launches vicious personal attacks.
