1) a terminal disease that can kill you in an instant, or just torture you. if this disease gets in your body, you will not know it at first. BUT the torture sign is, when the person turns into an asshole. THEN the disease turns that person into a pink chicken. Then you get all your friends together, and you all get suicide thoughts. So you all jump off a cliff.
ex 1:
person 1:"hey, why is nick being an asshole?"
person 2: "because he got TBI."

ex 2:
person 1: um, why the hell is dominic a pink chicken
