fan-plosion
A fan base of/for (example: a recording artist), responding to a post or tweet in an angry, insulting hate-driven manor, en masse, and all with the same insults, put-downs and misunderstandings - all in a percieved "protection" of their beloved Star from being "wronged" in some way by author of the post/tweet.
When Emma Watson partially bared her breasts for a magazine cover, Beyonces "Beyhive" had a fan-plosion on Twitter calling Emma a hypocrite.
