twilight effect - this goes for any crapy book you ever read, and for some reason you cant help but read the rest of the books, and watch all the terrible movies that they make.
Person 1: doctor for some weird reason i cant put this harry potter book down, and ive been watching the goblet of fire every day with my 12 year old sister for the past week.

Doc: well Person 1, you have a sever case of the twilight effect. now i suggest you go home and burn all your Ron and Harry dolls along with your novelty glasses and fake scar before you turn into a total faggit.
