When someone says something and its thrown back in their face or realize they messed up and cover it up by saying "It was a joke man" or "I'm just kidding bro". They proceed to yell calm down and make you look like the bad person in the conversation. These people can be defined as Douchebags for their crappy humor
Guy 1: No offense, but you sound like a faggot, Just kidding *laughs*
Guy 2: Why do you think that's funny? My voice is just like this, you dick
Guy 1: Dude I was just kidding man, calm down
Guy 2: Nice Douchebag humor Jimmy
