verb & noun: when a member/s of the cast/crew of a movie-shoot share info./fun-stuff on Twitter --
derived from Milla Jovovich's tweeting from the set of "Resident Evil: Afterlife" in 2009.
Milla occasionally posts on her IMDb board - but it's in her tweetoviches that she really communes with the fans.
A person who uses Twitter way too much, think it's the best thing in the world and fills up your queue with crap. They tweet about what they're eating, when they take a shit, and other banal, boring and otherwise vapid drivel.
