Mac Miller is the fuckin' man for multiple reasons.
1. His music is the music of a generation. It got me through high school, college, and still gets me through today. RIP.
2. He was a diehard Steelers fan.
He wasn't just a t-shirt fan, and even if he would have been I don't give a shit. This video of him throwing out a fan at a concert for screaming "fuck the Steelers" shows you how ride or die this dude was for the black and gold.
I would say that kid was a Ravens fan, but I've decided for sure that he was a Browns fan.
