Often used in Argentina to describe people who wear dark clothes, make-up, that could easily be goths, some sort of punks, etc. They usually go out in big groups (more than 3 people) at night, generally "depressed", and with the thought that they dont belong to society. It also doesnt aply to the sort of music they´re interested, only to the way they look/dress. Its common among them to only relate between "Darkies", not very sociable.
