Obie goobie
It’s what you say when you're too dumb to know what you're talking about. It's like a baboon wearing a crown.
I said 'Obie goobie' when I got yelled at for eating my homework.
My dog barked 'Obie goobie' when I tried to teach him to dance.
My uncle said 'Obie goobie' when he fell off a chair.
