notcore 

The very near opposite of the word hardcore. Usually applied to things that are supposed to be hardcore, but just come off as lame wannabes. Or, something so anti-hardcore that it is just notcore.

That new band, "Screaming with Emo Breakdowns" is so lame, it's just notcore.
All his friends are metalheads, I can't believe he dresses so notcore.

netcore

People who sit around on the internet all day talking trash acting tough and hardcore. Computer nerds, Elitist gamer assholes, and just regular computer junkies who feel superior because they know more than somebody else ONLINE and feel like they have to terrorize them.

Ex1:

"i'm sick of all these netcore kids sitting around talking smack to all the newbies"

Ex2:

ComputerNerd: Hahahaha faggot you don't know where the F1 button is, fucking noob.

ComputerIlliterate: Shut up you fucking netcore asshole.

Noncore 

1) Non pornographic material that is used in erotic context.
2) Pretending to have sex / dry humping.

1) John is a porn addict who wants to overcome his addiction, so he masturbates over noncore porn, usually a blank computer screen.
2) I wanted to impress my friends at a house party by seducing a hot chick, so I locked myself into a room with her and we had noncore sex while my friends listened behind the door.
