Internet Bipolar Disorder, or IBD, is when someone is all chill on the internet, and then something such as a thumbs down on a YouTube video, a loss on an online game, or criticism on a forum makes them go crazy. Symptoms of IBD include a sudden barrage of insults, sudden self-hate or saying they are leaving.
