Someone who thinks they're the best and ONLY them. They frequently act like everyone is below them and in arguments never admit that they are wrong due to the damage it might do to their ego.
They hardly laugh, thinking that laugh is for the weak and the only time they do is when it is to laugh at someone.
In their minds they are "the best" and that they "know best".
A possibility of this behavior is due to sexual frustration.

Vladislavian: What are you talking about?!?!?! This lighter uses NASA fuel!!!! It probably costs more than your car!!!
Arin: Dude, there's no way they put NASA fuel in this shitty lighter.
Vladislavian: They do!! I know best okay?!?! You wouldn't know 'cause you're not like me!!!
