The Greasers and the Socs are the two rival gangs in Susan Hinton's teen novel "The Outsiders." The Socs (short for socialites) are mostly rich kids from wealthy families--preppy types with nice clothes and flashy cars. The Greasers are poor kids from the wrong side of the tracks with long, well-oiled hair and black leather jackets. Both groups are outcasts from middle class society, and both groups feel they are outsiders from their parents and other teens their age. Both groups like to fight to decide their conflicts, and the occasional weapon is not frowned upon.
