A Bovver Boy, known as a Skinhead, is a subculture that started among working class youths in the United Kingdom in the 1960s. The first skinheads were greatly influenced by Jamaican rude boys and British mods, in terms of fashion, music and lifestyle. Originally, the skinhead subculture was primarily based on those elements, not politics or race.
The Characters in this game are based on these bovver boys.
