The hubris it must take to slap another dude in the face with a greasy slice of pizza and then turn your back on him after YOU TELL HIM to calm down. Dude was cocksure times infinity. So confident nothing would happen to him. That is, until the guy in the blue hat realized there was violence living inside him and he had no choice but to knock him the fuck out. Honestly, there was no other kind of retaliation on the table. Someone slaps you in the face with pizza, you nut up and cold cock that motherfucker. And if his back is turned…happy fuckin’ birthday to you.
