nafarius
A bunch of people who all think they're the best at everything. They argue about stupid stuff and then claim they're winning.
I'm in a nafarious club. We argue about whether toast is better than bread. No one cares, but we all still argue.
My friends are nafarious. They think they're the best at everything, even though they lost the last video game match.
My boss said we're nafarious because we all say we're the best, even when we're clearly not.
