In reality, very, very few of these people exist. Most of them are either already idiotic, psychotic fans or have been driven away by the fanbase's stupidity (thank god).

Beliebers (fans of Justin Bieber) often act the same way as Directioners, and target their rage towards "Non-Beliebers".
Directionator: "woah... chill out. And, aren't you, like, 11?"
Everyone Else: "Who cares."
The idiot part of the fandom uses this word to describe "fake fans"
Warning: they are idiots.
