A conversation consisting entirely of 140 character-or-less "tweets", or Twitter updates, on the micro-blogging website, twitter.com. Twittersations rarely contain legitimate Twitter updates and are instead more of a slower form of instant messaging.
Jack: @Jill How was your Holiday?
Jill: @Jack It was great, we had lots of food and drinks! How was yours?
