Social Flat-line 

A term stemming from two seperate lexical choices one of which is 'Social' to be defined as relating to human society and its members and 'Flat-line' which is a medical term to show the absence of heart contractions or the disappearance of the rhythmic peaks displayed on a heart monitor.

In this sense the conjoined term means the 'dead sector of society' So to speak : Nerds, emo's, paedophiles and so on, people who are marginalised and ostracised from society.

Flatliner 

A mindless person or someone with no personality; gives blank stares, especially when presented with ideas or facts that should arouse some sort of reaction in a sentient being. Basically brain dead or mentally challenged. It would be improper to use this against someone who has a real diagnosed disability of course. More like, if you meet someone in a professional capacity whose title suggests they are intelligent, but really they just stand around looking dumb.
