Reminiscent of a speed freak (aka: the tweeker) it is one who's OCD about memorializing everything they do at any given moment on Twitter; that is, one who tweets incessantly, constantly and/or needlessly.

Candy: Hello?
Sam: Hey, babe! It's me. Just callin' to see what you're doing tonight. Wanna go out?
Candy: Wait a sec...(tweets this call)...check me out on Twitter. I just twatted you (giggles).
Sam: Uhhh...I'm driving right now...I'm not at a computer.
Candy: Oh that's ok. Check it out when you get home. Seeya (CLICK).
Sam: What the f...?! I gotta dump that Goddamn, tweetfreak!
Posting many "tweets" on twitter (sometimes facebook) in rapid succession, whether said tweets were important/relevant or not.
JoeBloggs: I just ate a piece of cake (10 seconds ago)
JoeBloggs: That was damn good cake (7 seconds ago)
JoeBloggs: Damn, now I'm thirsty, might get a drink (3 seconds ago)
JoeBloggs: Mmm, pepsi. Goes down good (just now)
That, ladies and gentlemen, is an example of tweetarrhea
Tweetorrhea is a communication disorder, expressed by excessive typing of tweets regardless of the meaning and the value of the message. Tweetorrhea is a newly discovered illness and their causes remain poorly understood, however some theories emerged about their connection with low self-esteem and inability to build real life relationships.
John is suffering from tweetorrhea, harasses me five tweets per minute, my phone still buzzing.
