The term 'Petty GANGSTER' is a combination of two words, 'PUNK' and 'GANGSTER'. PUNK is a subculture that emerged in the mid-1970s, characterized by anti-establishment views, non-conformity, and a DIY attitude. PUNK music often has a fast tempo and aggressive lyrics. Gangsters are criminals who are involved in organized crime, such as racketeering, extortion, and drug trafficking. Petty gangsters are criminals who are involved in smaller-scale criminal activities, such as shoplifting, vandalism, and pickpocketing.
