Twaddiction

Being addicted to the social networking site Twitter, frequently "tweeting" pointless updates about your life

Patient: I'm on Twitter all the time! First thing in the morning, last thing at night... The people following me know more about me than my own family do!

Psychiatrist: I think you may have a twaddiction. Do you tweet singular nonsense things like "lol" and ":)"?

Patient: Yes!!

Psychiatrist: Yeah, it's a twaddiction... I'm just not sure it's curable...
