DT 

Donald Trump
A braggart, trumpeter, windbag, blowhard, a duplicate of Cliff Claven the fictional postal worker on the TV show Cheers played by the actor John Ratzenberger as the bar's obnoxious know-it-all character who was so delusional he believed his own incessant lies and bullshit stories

That guy is the DT braggadocio of this crowd. He doesn't care about truth, he thinks if he says it, that's enough to make it a reality, at least in his mind, even when he's describing his own reckless careless vulgarian behavior.
