Kakavanin
Kakavanin is a Bulgarian way of saying you’re a total loser who thinks everyone else is stupid.
My cousin is a Kakavanin. He doesn’t even know what a computer is but still thinks he’s the smartest guy in the world.
My neighbor is a Kakavanin. He doesn’t mow his lawn and still says he’s gonna be a famous singer.
My dog is a Kakavanin. He doesn’t do anything but bark and still thinks he’s the king of the house.
