23.
A new group (like Yuppies) in their early to mid twenties. They may or may not ever bathe, and fight the system. They usually have stringy hair or dreadlocks that need to be weed-eaten in order to be removed. They hate authority, although they mostly live off of the government in the form of food stamps or welfare. They travel in broken down vans, or by cardboard signs. They have enough dirt that if they washed off in the ocean, the dirt may form a small island.
Great, a group of dirties just pulled in the parking lot.

(Noun form):
A younger person who is a waste of space, has no marketable skills, is not overly attractive or hygenic, is extremely loud and obnoxious, and typically has a drug and/or alcohol addiction. They usually travel in packs that ride around in a shitty, beat-up car together. Their hobbies include showing up and ruining your friends' parties. Attempts to try and curb dirty participation at regular-kid parties have been made by attaching "no dirties" requests at the end of party invitation texts/facebook messages, but it is an uphill battle. The best hope to fight dirty-ism is by hoping that they have to move once their welfare runs out/they can no longer make thier house payments/their dads get busted for drug possession.
