This is just crazy that the guy - who has headphones on and shouldn't be bothered by you know - other people on the train (because that's just normal as fuck) goes this insane.
Sure his language is racist as fuck - but just the fact that he's got a hair trigger - that already tells us a lot too and apparently he also got in their face as well.
Life must really actually kind of suck to be that angry.
But you know - fuck him because if that's the way you want to live your life I'm guessing a heart attack is waiting around the corner...
