Feederism has been described as “a fat fetish focused on erotic eating, feeding, and gaining weight” [1]. There are two types of people who exist within this fetish culture: feeders and feedees. Feeders are people who get sexual pleasure from feeding other people and seeing them gain weight. By contrast, feedees are people who get sexual pleasure from being fed by others and gaining weight.

Feederism has been described in the psychological literature as a paraphilia—a term that means having an unusual or uncommon sexual interest.
