a clown - A clown is the worst person you can be, you're stupid, you'r

A clown is the worst person you can be, you're stupid, you're loud, and you make everyone around you tired of you.

My neighbor is a clown because he talks to his plants and yells at the mailman.

My friend is a clown because he wears a hat and a cape to school every day.

My brother is a clown because he thinks he's a superhero and tries to fight my dad.
