Noun. The new shape your chipotle burrito takes on when you take all the foil off early and it explodes into your bowl below, requiring you to use a fork or spoon to put all of the amazingness back onto the tortilla, and take the ends of the tortilla with your fingers to a point in the middle. When lifted by this point the tortilla resembles a diaper, and the ingredients falling out of the corners resembles fresh steaming baby feces.
Cameron: "Good job at taking the foil off your burrito too early Aaron."
Aaron: "Don't worry dude, when it all pours out I'll just make a Chipotle Diaper."
