Narcissistic Facebook Disorder 

When somebody obsessively trolls the Facebook status updates, comments, photographs, video posts and likes of their Facebook colleagues and manages to interpret every post as having a go at them. This is generally followed by a spate of angry personal messages from any one of their several fake accounts to generate a perception of false support from their 'friends'.

Person 1: "Man, that Meg has posted a photo of her new labrador puppy. Do you think she's hinting that I have breath like a dog?"

Person 2: "Dude, you have Narcissistic Facebook Disorder for sure".

It is like you feel a need to go to your Facebook homepage every now and then even you know that you got nothing much to do there.

"I don't know, I just feel like there's a need to use it."
