A carbivore /ˈkɑrbɪvɔər/ meaning 'carb eater' (Latin, carb meaning 'carbohydrate' and vorare meaning 'to devour') is an organism that derives its energy and nutrient requirements from a diet consisting mainly or exclusively of starches, such as french fries, cereals, breads, pasta, candy, jams and desserts. Animals that depend solely on starches for their nutrient requirements are considered obese. A carbivore that sits at the top of the foodchain is an obese SOB, or fat bastard.

A fourth classification of animal in the food chain behind Carnivore, Herbivore and Omnivore that eats only garbage.
Every time I put my garbage outside in the garbage can, my dog knocks the can over to eat the garbage inside. I never see him eat anything but the garbage, he must be a Garbivore.
