1) A condition resulting in tweeting frequent, short bursts of the most minute daily activities. 2) The collection of tweets from a group of people about the same event, resulting in highly repetitive clumps of observations.
1) Oh, I had to unfollow her, she had a bad case of twitterhea flooding my iPhone.
2) since I wont physically be at #railsconf this year, i'll attend virtually by lurking in the irc channel and consuming the twitterhea all day.
symptoms: obsessivetwittering in a short time span (often pointless tweets posted just to pass the time), twitching, putting @ signs in front of a person's name before texting or emailing them
diagnosis: one of your followers will say something along the lines of "holy shit, STOP!"
treatment: no cure; treatment includes throwing your phone out of the window and running over your router with your neighbor's lifted Ford F350
An explosion of twitter messages that consist of sporadic "twarts". The messages are irrelevant and take up your entire twitter wall. These people usually average about 30 tweets an hour.
"Good morning!" or "Hows everyone doing?" or "Just ate some mashed potatoes off the carpet. Woohoo!"... These are all examples of someone with a case of twittarrhea.
Basically anyone with more updates than followers. Some would go so far as to qualify anyone who tweets more than 6 times per day as someone suffering from Twitterhea. There's no way your life is that interesting!
