OCTD

Known among "medical" circles as 'Obsessive Compulsive Twittering Disorder", the symptoms of this impulsive disorder include: the compulsive desire to stay within a five foot radius of any device connected to Twitter and exhibiting anger at whomsoever disturbes them while posting updates. This neurological disorder can be completely cured by pulling the plug on the internet connection in the diseased person's home.

"Mike, come downstairs and have some dinner!"
"No, Mom. I'm retweeting an update made by Jeremy."
"I'm worried about you OCTD, so I've had your father disable all internet access within our home."
"Nooooooooo!"
*gunshotgunshot*
"I don't have OCTD!"
