The common signifiers of sukeban (described by the Japanese police in 1980s pamphlets as "omens of downfall") include brightly dyed or permed hair, and modifications of the school uniform such as wearing coloured socks, rolling up the sleeves and lengthening the skirt. Sukeban are reported to engage in activities such as stimulant use, shoplifting, theft, and violence, but if arrested, they can be charged with the lesser offence of "pre-delinquency".[3] The word sukeban was originally used by delinquents, but has been used by the general population since 1972.[2]
