Bounder

A "Bounder" is a term from British slang used to describe a person, usually a man, who behaves irresponsibly, disrespectfully, or with a lack of manners—often towards women or in social situations. It implies someone who acts in a selfish, rude, or unprincipled way, disregarding social norms or others’ feelings. The term can carry a tone of disapproval, highlighting inappropriate or uncivil behavior that tarnishes personal or social reputation.
