IPA: /ˈbaʊndər/
KK: /ˈbaʊndər/
A man who behaves in a rude or dishonest way, often lacking good manners or morals.
He was considered a bounder for his deceitful actions at the party.
Bounder → The word originates from the verb 'to bound' (from Old French *bondir*, meaning to leap or jump) combined with the agent suffix '-er' (meaning a person who). A bounder is thus a person who leaps or bounds, often used in a derogatory sense to describe someone who behaves in a socially unacceptable manner.
Think of someone who 'leaps' or 'bounds' into situations without regard for social norms — that's why a bounder is often seen as someone who behaves poorly.
