Rambling incoherent twitter postings which are made usually while under the influence of drugs/alcohol/self-importance. Often posted in rapid fire and contradictory to previous posts. Well known crack tweet-ers are Lindsay Lohan, Tila Tequila, and Courtney Love.
An example crack tweet from Lindsay Lohan this November (in rapid fire)
"When does âgoing for a driveâ turn into âwalking into teddys with @carlosncharge and a girl"
"Too bad I can catch someone in a lie when I heart voyeur"
"Jess s is with kellun hahahahahahaha"
" so much for s not being âpublicâ guess fame is better with premiere kids."
or
"Did you see the crack tweets that Courtney Love posted about losing custody of her daughter?"
