Slob, for starters: messy eating, belches, farts, even bodily functions. Also the various methods and ways in which someone can be coerced into gaining weight: manipulation, brain drain, hypnotism, coercion, that sort of thing. Sometimes adult-baby stuff but only when related to weight gain.
Basically fat is my main fetish and I like various other fetishes only insofar as they interact with and enhance the idea of girls being fat and gaining weight.
