daft dildo
A person who’s not only stupid but also thinks they’re the best at everything. Like a burnt-out lightbulb that still thinks it’s bright.
He said he could beat you at chess with his eyes closed. You said, 'You’re a daft dildo.'
He tried to explain gravity with a pizza. You called him a daft dildo.
He said he’s the king of the world. You said, 'You’re a daft dildo.'
