blueflamewolf 

Can be used as a proper noun when capitalized (Blueflamewolf) or as a verb.
The noun can indicate someone who has lost all touch with reality through increased involvement in their fanfic, usually resulting in self-inserts in fics the author honestly believes to be true, usually due to psychic powers on the author's part. Such a person may sometimes amass a small cult following on certain fanfiction archive sites, such as fanfiction.net. The verb form may be used to indicate the process of becoming or the continuing existence as a Blueflamewolf.
The word's etymology comes from the screenname of the first of its kind.
"Sheila's such a Blueflamewolf. She actually scratched my eyes out the other day when I told her that The Phantom of the Opera/Legolas/Willy Wonka/Darth Vader wasn't real. I'm blind now."

OR

"Sheila, you've got to stop blueflamewolfing like this! We suggest you seek intensive therapy. Gigi's blind because of you!"

OR
