Twilosis is a disease that makes the person irrational and psychotic when talking of any sort of black book with white and red things on it.

(1). Talking about anyone named Edward or Robert
(2). Wearing a shirt that has a line from the movie/book Twilight
(3). Pale or fat

To rid your friend of Twilosis:
(1). Take any book that you find in their backpack/home called Twilight, New Moon, Eclipse or Breaking Dawn and burn them.
(2). Place your head on their chin, their head and twist as hard as you can.
(3). Tell them that this Edward person isn't real. (They might turn into a Twitard if you do this)
My friend came down with Twilosis, and I tried to save her... She's now a Twitard.
