Orginated in the UK during the 1950s. British cafe race motorcyclists, Rock and Rolls music blarring. They wore whiteor black t-shirts, with the sleeves rolled up, Levis 501 jeans, motorcycle boots, winkle pickers. Basically scruffy masculine bad-boy image. Working class, therefore NOT cool to follow fashion yet here we are a fashion blog talking about them!! Mods and Skins would call Rockers grease or greaser as and inslut (burn). Which leads on to the Mods and Rockers rivalry publisised by the media, think 2pac v Biggie. There was nothing there til the media got involved. Pigs.
