A music and fashion subculture started in the mid-late seventies in the UK. Seventies teenagers developed their own dress code based on 1950s American Juvenile Delinquent novels and Hot Rod B-movies.
Puttin distance between themselves and the older "Teddy Boys" who attended the same clubs and dances at the time.
Their taste in music was for the more primitive hillbilly-rock hybrid "rockabilly" that kicked off in the mid fifties at the same time as its more succesful and commercial sibling - "rock and roll".
The rockabilly scene still exists today.
He must be a rockabilly, his turn-ups are huge!
