暴徒 (bào tú) is a compound noun meaning 'ruffian' or 'thug' — a violent, lawless person who often acts in groups to cause public disorder, damage property, or harm others. The first character 暴 (bào) means 'violent', 'brutal', or 'sudden', evoking aggression and lack of restraint; the second character 徒 (tú) means 'follower', 'disciple', or 'person', but in compounds like this it often carries a negative connotation, implying someone defined by undesirable behavior. Together, they form a strongly pejorative term for individuals engaged in mob violence or criminal intimidation.

This word appears frequently in formal news reports, legal contexts, and official statements describing civil unrest, riots, or organized vandalism. It carries strong moral and legal judgment — never used neutrally or affectionately. While it can refer to individuals, it’s more commonly used collectively (e.g., ‘一群暴徒’ — 'a group of thugs'), reflecting its association with collective lawlessness rather than isolated misconduct.
