One who adopts the practice of exploiting social programs and resources (e.g. Welfare, section 8, ect.) as a lifestyle in an effort to evade work. Because they are neither employed, nor seeking employment, dirties have an abundance of free time most often used in a self-indulgent, non-constructive manner. For recreation, dirties will loiter around cities during all hours of the day, often under the influence of drugs and alcohol. They often wear flat-brim hats, tank-tops or oversized t-shirts, hooded sweatshirts, baggy pants, skateboard or basketball shoes and have extremely poor hygiene. They are also known to purchase an excess of items such as soft drinks, sugary foods, chips, alcoholic beverages, and tobacco products with taxpayer money in the form of a plastic card (EBT, SNAP, ect.)
Make sure to roll up your vehicle's windows almost all the way, so it lets the air come in, and keeps the dirties out.
-Hey John, do you think that man over there is on his lunch break? I see him walking the streets every day.
-No Harry, that man has a sideways flat-brim hat and a wife beater, he's just a dirty.
