people use 'u mad bro' like it's some great insult. people get mad. it's a human emotion. it exists for a reason. it's not a glitch. anger is a motivator, and a damn good one. get mad, folks. use that energy. most people aren't mad enough these days.
yeah i know exactly how it's used, which is exactly why i'm telling people it's ok to get mad.
i look forward to the day when i mash some little punk's face in because they trolled the wrong dude. "yeah, i'm mad and now you have to pick your teeth up"
