A {{Fandom}} that is dedicated to hating a work or author, instead of celebrating it. Sometimes they view the work as SoBadItsGood (to the ire of more traditional fans); at other times, they just loathe it outright, but enjoy making fun of it. Some works have the dubious honor of producing hatedoms larger than their traditional fanbase.

Of course, for optimal snark it's best to have actually read/watched/played/listened to some of the hated work, but some people have gone so far as to produce derivative works capable of standing on their own with only a general knowledge of the original. On the other side of the equation are people that view the work several times over, memorize all the [[AllThereInTheManual supplemental minutae]], and [[WhatDoYouMeanItsNotDidactic write senior thesis level dissertations over the underlying themes and structure]] because [[SeriousBusiness they hate it so much]].

In cases where members of a Hatedom also hate the ''fans'' of said work, they would be {{Fan Hater}}s. It should also be noted that a Fan Hater isn't necessarily a member of a Hatedom; it is quite possible to be a fan and hate other fans of said work, a phenomenon that can also be blamed on the FanDumb (i.e. being exposed to too much of it). Fans of a work are likely to view its Hatedom as a HateDumb.

When you have a hatedom within a fanbase, it's called BrokenBase. When you hate something that wasn't aimed at you in the first place it's a PeripheryHatedom. Typically, works that are more well-known are more likely to produce a Hatedom. After all, it's much easier to ignore more obscure works that you happen to dislike -- and, if not many people have not even ''heard'' of the work, then finding a fellow hater to commiserate with would be next to impossible. Thus, this trope is closely related to HypeBacklash.

If it's only a character that has the hatedom, what you've got is TheScrappy. If the fanbase hates the character but the creators love it, you have a CreatorsPet.
