Chavs are those white trash ones with babys at 16years of age and.....sportswear?
Yes, track suits! Those are the ones! Do you have people like that in Sweden? What do you call them?
Hm...we call them white trash, as far as I know...tracksuits are seldom seen in Stockholm nowadays though. Maybe some hiphop-variation.
Raggare, as TheoK mentioned are basically a mix between rockabillys and hillbillies. A subculture of their own, mostly seen in the rural areas of Sweden.
