Skids are those dirty bags who hang around in the darkest, dirtiest corners of the school raving about who they want to kill the most because they cant fit into society. Although the acronym may lead some to believe they are truely street kids, skids have homes and most likely families to go home to so choosing to be nasty is their own fault.
