Narcissist

An asshole thinks they’re the best person in the world. Will probably look up their name on UrbanDictionary just to see how good they are.

Mark: Did you see what it said about my me? It says “He's the definition of amazing. He defines the word friend, too. He'll always be there for you. He defines hard working,” and it’s all true! I think they left out the part about me being sexy though.
Jason: Fuckin’ narcissist.
