A disgustingly fat person who (usually while eating a salad) makes a comment about the unhealthiness of something you are eating.

I was trying to enjoy my hamburger but Lena kept talking about all the fat and carbs it contained while shoveling pile after pile of salad in her mouth. That bitch has a lot of nerve- she weighs 425. She's such a fatocrite.
