Myspace Syndrome 

A behavioral offset(though not necessarily a detrimental one) in which a person will treat a random person they meet with(and probably helped with once or twice in their lives) as if they were best friends. Typical Myspace Syndrome can be identified in superfluously affectionate behavior(ie: often demanded big hugs when they meet, etc)

How the two meet is by no means limited to just adding each other as friends on Myspace/Facebook/etc.

Guy A: Hey! :D
Girl: OMG, it's (insert name here). Hi :D

*big hug*

Guy B: Man, look at him. He's only met this girl one day last month ago when she asked for homework help, and now they act like there's an unbreakable bond between them, like every other girl this guy met. He's got a serious case of Myspace Syndrome.

she/he looked better on facebook/myspace syndrome 

When one uses either facebook or myspace to look at people or try to meet people and they see the picture of a good looking person. Once they meet up the one that thought the person on myspace or facebook was good looking, find out that that person is infected with "She/he looked better on facebook/myspace syndrome".
