An individual whose dietary restrictions are only crap food i.e.: junk food, fast food, greasy food. Crapitarians have little regard for the health of their own bodies and, subsequently, have very limited "foods" that they can/will eat.
It is amazing how Ross is still living, considering how much of a hardcore crapitarian he is. The guy eats KFC double-downs for breakfast!
A person who lives on a diet of mostly junk food. Their diet includes ice cream, cookies, diet soft drinks, and candy bars; it excludes poultry, meat, and fish, but some crapetarians eat dairy {lactocrapetarians}, eggs {ovocrapetarians} or both {ovolactocrapetarians}. Motivations include, but are not limited to ethics, parental defiance, garbology and health.
A vegetarian who doesn't eat fruits, vegetables, or anything remotely healthy. Instead they eat an obnoxious amount of carbohydrates and fats.
Person 1: Monique said she's vegetarian but i haven't seen her eat a single fruit or vegetable all day. Instead she's been eating pizza, lasagna, and cheesecake.
Person 2: Clearly she's a Carbetarian!
