Obsessive-Fan

Obsessive-Fans are the scary kind of fan. They know EVERYTHING about their fandom. They have it memorized. Obsessive-Fans blow a fuze if they miss a single movie, blog, T-shirt, etc, of their fandom. They take it RIDICULOUSLY serious.
Obessive-Fans are avoided by Proper-Fans and Casual-Fans, though Psuedo-Fans latch onto them in an attempt to look like Proper-Fans.
Note: It is possible to be an Obsessive-Psuedo-Fan, becoming Obsessive with every new trend. It is also possible to recover from being an Obsessive-Fan, though it is usually very difficult.

Jill is an Obsessive-Fan of Twilight. She knows every speck of trivia, and if someone so much as gives her a weird look when she's going on about Twilight, she'll have his head. Literally. Jill's room is full of Twilight posters. She has mutltiple copies of each book. EVERYTHING in her life revolves around Twilight.

obsessive obama disorder 

When an individual becomes so obsessed with Barack Hussein Obama administration, (s)he cannot function without listening to a perpetual all-star rimjob delivered by any of the following men: Mr. Keith Olbermann, Mr. Rachel Maddow, or Mr. Joe Biden.

I noted the presence of Obsessive Obama Disorder when I turned on the television only to find Keith Olbermann on MSNBC fisting himself with a doll that had the face of Barack Hussein Obama.

obsessive consumption disorder 

The new OCD: It is when people tend to overeat or over consume a product, such as, gasoline.

She is fat because she has OCD.

Why is she fat if she has obsessive compulsive disorder? Doesn't she do a lot of cleaning and stuff?

No. It's obsessive consumption disorder. The new OCD that is plaguing Americans. She cannot stop consuming unhealthy food. Plus she gets no exercise and overuses gasoline by driving her fat-ass everywhere.
