Tweefault 

Like a default picture on any other social-networking site, but since Twitter is just that cool, it has a different name for your default picture. Behold, a "tweefault."

I know, but don't hate. My Tweefault is the cutest!

Tweetfart 

When you start typing a tweet and forget what you were typing (similar to a brainfart when you forget what you were about to say)

Dude, I just had a tweetfart... totally forgot what I was tweeting!

Tweetfart 

a lapse in the thought process while tweeting that causes you to post something that maybe you shouldn't.

@Kanye :I know I said I'd bite my tounge but 6 AMA noms for a 19 year oLd?!?! Two albums!? Fuck that!!!!!

TMI can lead to tweetfarting. Here is an example:
@ruthakers They canceled school and reminded everyone to "Prepare for a blackout" I've got 2 bottles of Vodka and percocet Blackout is *so happening* (definitely a tweetfart)
