I think this song is the long-needed self-evaluation of an asshole.

The "One night at the disco..." verse is an incident of rejection which sets off this self-evaluation. He thought he was King, but "some dude" took the lady he was eying, resulting the in taking a look at himself and asking, is he really King?

The second verse is where the self-evaluation starts. "I see you come here..." is not talking about someone else; he is talking to himself. He realizes he can't keep acting like this, going to clubs, drinking, chasing after women, making an overall ass of himself, basically being a "bro."

But the chorus comes in. His egotistical manner takes over again, and he reinforces his previous belief that he is King. I take this two ways: either he really is reverting to his previous way of thinking, or maybe the chorus is what he is projecting, but the verses are his inner thoughts and regrets. He knows he shouldn't act this way, and he's sorry for it, but he can't stop.

The song continues on in this manner, verse being regretful and self-evaluating, while the chorus reverts to his asshole attitude.

He wants to stop pretending to be King and "act like a grown man," but can't because either he truly does feel like he is King, or he realizes he has dug himself in too deep a hole, surrounding himself with "losers" and "babies," and thus has no one to pull him out, as enforced by his final repetitions, "I'm King, I'm King, I'm King..." almost like he has to convince himself that he truly is King.
