Hairless Ape
A human who looks like a monkey with no fur, and acts like they're the king of the jungle. Also, they're the same species as Howard the Duck, who is also confused.
My brother said he's a hairless ape because he forgot his pants.
My teacher called the class hairless apes because they were all distracted.
My friend's parrot says 'hairless ape' every time I walk in.
