Twitterstorm definition: A Twitterstorm is a sudden spike in activity surrounding a certain topic on Twitter. Using a certain and ideally an original hashtag, the tweet quickly spreads as people are notified of the message and then reuse the hashtag with subsequent retweets and tweets. The goal is to trend (at least locally) to gain attention. (Source = Techopedia)
