By Not cast bonding

Doof is food backwards. The term is used to distinguish doof from actual food. Doof is the the stuff sold to go in your mouth refined from food, usually designed and engineered to cause you to crave more of it, usually through salt, sugar, fat, convenience, or other engineering.

Mike: I can't stop eating all this doof! I know it makes me fat and feel horrible, but I just keep wanting it! Josh: That's because it's designed that way - here, have some real food. It'll make you feel better.
