mactitties
You eat so many McDonald's burgers your boobs look like they're made of ketchup and your stomach is a disaster. People who can't stop eating fries get this name.
My brother got mactitties after eating a whole Happy Meal every day for a week.
She got mactitties and now she's the fattest kid in the class.
He got mactitties and now he's the target of every joke.
