Meyer complex 

(n.), a mental disorder that affects only women, mostly those in their teenage years. A woman with the Meyer complex feels that she is not complete without a boyfriend or husband by her side. In some cases, the disorder is so strong that the woman will not feel that she has the strength to live without a boyfriend or husband.

The Meyer complex is named after best-selling author of the Twilight series, Stephanie Meyer. In her book series, the main character (Bella) has a substantial case of what is now known as the Meyer complex.

Stephanie tried to kill herself after she broke up with her boyfriend yesterday. John found her trying to hang herself in the park and now they're going out. She's got a really bad case of the Meyer complex.

John Mayer Complex 

attracting and using people for sex or to push your face into the spotlight, essentially using someone for your own gain

Getting a woman (or man) to have sex with you and then tossing them to the curb when you've had your fill of them. Like John Mayer most recently did with Taylor Swift, Jessica Simpson, and other major A celebs.

most commonly seen in men/women who are "players" or "rolling stones"

The guy who tells a girl she is beautiful and EVERYTHING else she wants to hear in order to bed her, then splitting up with her immediately after or shortly after which is a major asshole personality flaw known as the John Mayer Complex
