Twilititous 

a disease characterized by the uncontrollable urge to Facebook/Twitter/Blog/MSN/talk about anything Twilight-related. Sufferers are usually normal in appearance, but upon closer examination, faster heartbeat and dilated pupils can be observed. Sufferers will experience an increase in adrenaline upon any exposure to Stephanie Meyer material.

Dude, my girlfriend's got a total case of the Twilititous...she won't shut up about Team Jacob VS Team Edward and is constantly gushing about that stupid movie. she wants me to dress up as either a werewolf or a vampire the next time i do her. WTF. FML.

Twinititus 

The disorder of two people who aren't literally twins, but they act the same, think the same, and very often say the same thing at the same time. Many times these people are complete opposites in their appearance.

House of Night, Erin Bates and Shaunee have definite twinititus, but they're also called Twins by the people around them and call each other Twin.
