A Fandom that is dedicated to hating a work, idea, community or author, instead of loving it.
Of course, to have some form of credibility, it's best to have actually read/watched/played/listened/joined/followed to some of the hated work, but some people usually hate without having any knowledge or something parroted to them by another hater.
If you hate the fandom of a loved work, you part of a Hatedom.
If you hate the fans of a fandom, that makes you a Fan Hater.
A Fan Hater does not have to be part of a Hatedom.
Anti-Fans of a work are likely to view its fandom as a Fan Dumb.

1:The metaphorical drink that gives haters their ability to hate, just like Gatorade give athletes the fluids to compete physically. Combined by mixing the words "hater" and "gatorade". Hatorade is metaphorically the color "green" with envy.
2: the act of hating. sometimes called "drinking hateorade"
"Hey asshole! Stop drinking that hateorade and get your own bitch, you hating bastard!"
Someone whose hatred of some particular item requires that they spend significant amounts of time and energy describing and sharing their scorn. An anti-fanboy.
I can't believe what a twilight Hateboy Bobby is. He totally stays up all night talking shit on Twi-hard chartrooms.
