naitard
A person who's so dumb they think a chicken could be a president. They believe in nonsense that even a brain-dead donkey would throw a tantrum over.
My mom thinks the sun is made of spaghetti. I said, 'You're a naitard.' She said, 'You're a naitard.'
My dad thinks gravity is a lie. He's a naitard.
My brother thinks the sky is made of glitter. He's a naitard.
