A fucking retard
Someone who is so dumb, they do stupid things more than once, like a broken record.
My friend tried to text me with his nose. He did it again the next day. He's a fucking retard.
My brother tried to eat a whole cake in one bite. He did it again the next week. He's a fucking retard.
My cousin tried to fly a kite in a hurricane. He did it again the next year. He's a fucking retard.
