Jabalabadingdong
Jabalabadingdong is when you think you’re the smartest person in the room but you’re just being an idiot.
My friend said the sun is green. I told him he’s jabalabadingdong.
My dad thinks he’s a scientist. He’s just jabalabadingdong.
My cat thinks it’s a god. It’s clearly jabalabadingdong.
