F46
Someone who thinks they're the best at everything, but they're actually just average and a bit obnoxious.
My friend is an F46. He says he can beat anyone in the school, but he lost to my dog.
My neighbor is an F46. He yells at the mailman every day and still doesn't get his mail right.
My little brother is an F46. He thinks he's a superhero, but he can't even tie his shoes.
