Twilightified 

A verb that means to fall into a deep obsession with the storyline or characters from Stephenie Meyer’s Twilight Saga immediately after reading or watching it. This usually occurs in desperate, young women and preteen girls. A common trait you will find in twilightified fans is a substitution of these fictional characters for a real relationship.

“Once I saw her face after finishing the first Twilight book, I knew she had been twilightifed.”

“That girl was definitely twilightified. Did you see her Edward Cullen pillowcase?”
