Sukeban (スケバン/女番/スケ番) means delinquent girl or boss girl in Japanese, equivalent to the male banchō. A dictionary of Japanese slang says that sukeban only refers to the leader of a girl gang, not any member of the girl gang. 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. Another common signifier is the sukeban tendency to completely and utterly not give a shit. Sukeban will absolutely fuck you up and won’t even care.
