E Brain
A name for someone who's so dumb they probably think the moon is made of cheese and it's a conspiracy.
My cousin asked if the moon was made of cheese. I called him an E Brain on the spot.
My teacher said I was an E Brain for thinking the earth was flat. I still don't believe her.
He thought the sun was a giant light bulb. I had to explain it was a star. He's an E Brain.
