Threatening to stab someone because you're mad is pretty fucking immature. Claiming someone who promptly laid an ass whooping on you was "lucky" is also pretty immature. It's not like Dustin closed his eyes, threw one punch that somehow found it's way to Brandao's jaw rendering him unconscious. This guy says he wants to fight for his family and be a champion but comes in grossly overweight and childishly threatens a stabbing because of the way someone looks at you? This guy needs to really man up and get his shit straight.
You have to know what you don't know.
