so basically you've never actually been on /b/?
Oh I've been there plenty, probably more than any man ever should
However my view of /b/ is stuck around 2009 as I've had no urge to visit since then so if they've become a haven of angels in the last 6 years instead of a teeming hive of underage users trying to "troll" each other then I apologize
"u mad?" just strikes me as a phrase that someone who frequently posts on /b/ might go to whenever an appropriate situation arises and in my humble opinion it is the absolute lowest form of response next to grunting like a caveman
