n. A non-traditional (ie: non-sexual) def. of the word, meaning a person on a message board whose sole purpose is to take hits for a bigger/more respected poster, so as not to make them look bad. They will often suck-up to said bigger poster to the point where the entire forum labels them a Fluffer and not worth much more than an annoyed STFU
Fluffers usually work alone, but there are small cliques of forum Fluffers that will stick together to defend a celebrity or favorite genre (eg: emo), or game (eg: Halo)while not providing much more content than "You suck, n00b!!"
Pounding these fluffers into the e-pavement is like snacking on empty calories, there will always be at least one hanging around.
