A fatsexual is one who does not have any sexual attractions based on their targets hair color, age, eyes or other physical traits of that nature. Instead they are attracted to anything that is fat. Generally fatsexuals are also heterosexual they simply enjoy larger versions of what most other people find attractive. There are some fatsexuals that are so overcome by their love of cellulite that their alternate lifestyle causes them to become homosexual or even to attempt to fornicate larger farm animals or tubs of actual cooking lard.
