A person who's hometown is Chattanooga, Tennessee. A Chatt Rat must be a boozehound. All Chatt Rat's must respect Chattanooga and surrounding area's. A Chatt Rat's phone number must also maintain their original 423 area code, even if they move locations. A Chatt Rat must be better than any other city in the state of Tennessee. They are champion drinkers and smokers. They must also be able to distribute even servings of a Chatt Town Beat Down.
