A person with brown hair which is a couple shades darker than a blonde and a few shades lighter than someone with black hair. It has nothing to do with intelligence, amount of fun or anything else. It's only a hair color that can be changed by dye, lemon juice or sun light... Sometimes bad koolaid.
"Well since I'm a blonde and supposedly 'Stupid' by social standards, I guess I should drip over that table and end up fighting that brunette over there because we look different. Or, I could be the only person here with a definition and not an opinion"
