Believing you're the most cunning, clever, and brilliant person in the world, even if you're still wearing your pajamas.
My mom says she's the smartest woman in the neighborhood. She's wearing her pajamas at 10 a. m.
My brother thinks he's the most cunning person alive. He still uses a flip phone.
My dad says he's the best at everything. He can't even tie his shoes.
