I'm turning into a total insomniaddict. I watch Ferris Bueller's Day Off over and over every night instead of getting sleep.

3 definitions either you are unable to sleep because you do drugs like meth and speed or you cannot sleep until you smoke a blunt or you have FFI a rare and horrifing disease where you don't get R.E.M.
An example: I am a Insomniaddict I defined this word at 415 in the morning cuz it took this long to pick up a blunt sack. I know sucks right?
