Dirty kids are the kids in your high school or middle school that are very dirty. They are people everyone fear for some odd reason, and they usually don't smell very pleasent, and smell like they just fell off the back of a garbage truck. They are generally very poor, and hang out with other dirty kids. They always look smug, and many of them smoke weed. They like to skip class, and often like to cuss down people who walk by. These kids usually sit at their own table in lunch, in a corner. These kids like to dress in black, wearing old t-shirts with Led Zeppelin on them, and Jimmy Hendix. These kids usually wear loads of earings, and the girls have nose rings often. The dirty kids are not kids you want to be part of, behind your backs, you are secretly made fun of, and mocked all the time. Most of us just hate you.
-Why is he so pissed?
-He's not pissed, he just hangs out with the dirty kids!
The kids at your high school that wear the big chain pants from Hot Topic, wear Insane Clown Posse shirts, usually dye their hair stupid colors and draw on themselves. They usually give each other dumb nicknames.
