delinquent
Delinquents have come in many types in different times and places, but the stereotype tends to attach itself to whatever scary new subculture the kids have come up with recently: greasers in 1950s US, mods and rockers in 1960s Britain, punks everywhere since the 1970s.
The Japanese subculture includes specific depictions of delinquents, such as Sukeban, Banchou and Bousouzoku.
