Basically a non-artist formerly known as merely a conceited dude, had the walls between his &quot;knowledge&quot; of his greatness and the perceived reflections of it from outside (e.g. from movies and others&#x27; glam lives) collide. Collision fueled by a rage at everyone else&#x27;s lack of acknowledgement of his greatness.<p>madaxe_again&#x27;s summation is on track. But I don&#x27;t believe coke was necessarily involved - some people just have higher and growing concentrations of asshole within them.
