A fanbrat is a young, exceptionally disruptive fan of any series, or someone who behaves as such. Fanbrats are usually preteens or young teenagers, although not all young fans are considered fanbrats. The defining characteristic of a fanbrat is immaturity beyond what would be expected out of a normal fangirl or fanboy. Where a normal fangirl may behave marginally badly or be hurt if her work is criticized, a fanbrat will pull a full-on temper tantrum against the criticism in question. Sometimes it is possible to see evidence of such a quarrel in their fanfiction itself: real life fights may be depicted, and the objects of their frustrations dispatched callously.
