FABNERD
A FABNERD is someone who thinks they're a king but is just a regular guy with a bad haircut.
My math teacher is a FABNERD. He wears a crown to class and still can't solve algebra.
My neighbor is a FABNERD. He thinks he's royalty but he can't even cook a sandwich.
My friend is a FABNERD. He got a B and now he's king of the school.
