Those greasy kids who always come and trash "normal people parties". Often involved with drugs and alcohol and mainly cigarettes. The first step to being a skid is denying the fact you are actually one. The average skid has financial problems and possibly has no parents (which could contribute to skid behavior and lack of parenting). Majority of the skids take public transit or find strange places to hang out at late hours of the night lurking the streets. School is not something a skid enjoys so they either attend under the influence or not at all. The male attire of a skid often includes: white wife beaters or baggy jerseys, with baggy jeans and fake ed hardy. The female attire of a skid often includes: either dressing very slutty/unclassy or dressing very sloppy with dresses that barely pass your ass cheeks or ripped sweatpants with dirty stains all over them and skater shoes. Skids also struggle with hygiene and keep themselves clean. They are one step up from a hobo and like to steal things for money. Skids seem rebellious and wanting to start unnecessary fights, have troubles finding jobs since they are all street rats. Skids tend to travel in packs of 5-6 and carry many STI's. SAY NO TO SKIDS

Canadian definition: Commonly used to refer to someone who stopped evolving, and bathing, during the 80's hair band era. Generally can be found wearing AC/DC muscle shirts, leather jackets, and sporting a mullet. The term "skid" is in part derived from "skid row", which is both a band enjoyed by those the term refers to, as well as their address. See also white trash and trailer park trash
