The Davis Chileto is when a person passes out in a sleeping bag naked. This person proceeds to shit themselves, vomit, sweat profusely and urinate, all while rolling around in this mixture of like a hot dog at 7-11.
Remember last summer when Ted passed out on the couch in that sleeping bag and shit, pissed, puked himself? That was the worst Davis Chileto of all time....
