The event where an individual tweets a lot in a very short space of time about a series of unimportant and seemingly unconnected topics.
(n.b. this occurs often as a result of either caffeine highs, drunk tweeting and extreme boredom/procrastination)
Person 1: hey, did you see twitter last night?
Person 2: No, why?
Person 1: Tom got drunk and had a bad case of twitter-vom last night, it was hilarious.
