'A 16-year-old boy died over the weekend in the central province of Cordoba after being beaten by other youths, police said, adding that the victim was apparently attacked for looking like a "flogger," a popular new fashion in Argentina. Three suspects, two of them 16 years old and another who is 20, have been arrested for allegedly attacking the teenager, hitting and kicking him as he was leaving a discotheque early Sunday.
Precinct chief Oscar Criado told Argentine media that the victim was wearing "clothes that identify floggers," as Argentines call those who contact each other publishing photos on Internet social networking sites like Facebook and MySpace. "Flogger" comes from Fotolog.com, a photoblog social web site that is particularly popular in Argentina. Floggers usually wear tight jeans, canvas sneakers or skate shoes, colorful T-shirts, with a hairstyle that includes a fringe that tends to cover the eyes completely or partially, and is the same for girls and boys.
Other common characteristics include listening to electronic music and dancing in their own peculiar way. The most popular move, related to the French tecktonik and the Australian shuffle and the Charleston of 100 years ago, consists of rapidly spreading one leg, hitting the floor with the heel, and drawing the other leg backwards, and then quickly changing the position of the legs (spreading the other leg, and shifting backwards the one that was spread)...'
