nafarius
A gang of people who all think they're special. They make up their own rules and then get mad when you don't follow them.
My friends are nafarious. They made up a rule that you can't wear hats inside. I wore one and they called me a rebel.
I joined a nafarious group. They said we're special and we get to argue about the meaning of life every day.
My teacher said we're nafarious because we all think we're the best even though we're clearly not.
