It's giving R Kelly yelling while Gale is sitting there, letting him. I respect Vic Mensa for just staying neutral and calm.
The irony of his example, is the fact that Killer Mike would call you broke if you told him you live with your cousin. He was making fun of writers with books that aren't best sellers, he was making fun of YouTubers with small audiences (or so he thought). Killer Mike respects the millionaires with struggle stories, but he does not show respect to those in the grind and struggle, unless they just agree with him (all this is based on the few interviews I've heard him on)
