Oblivion NPC 

Braindead and acts like a robot in actual human interaction

both of these traits are shared with an NPC (non-player character) from the video game "Oblivion" hence the name.
The NPCs in this game are infamous for having the dumbest conversations and acting extremely robotic, snapping towards you if you engage with them.
These people will act just like in the game and are generally very stupid.

Paul: hello friend, would you enjoy a cup of coffee and a sandwich at the cafe for lunch, it would very much please me.
Friend: you are such an Oblivion NPC

Oblivion 

"There will come a time when all of us are dead. All of us. There will come a time when there are no human beings remaining to remember that anyone ever existed or that our species ever did anything. There will be no one left to remember Aristotle or Cleopatra, let alone you. Everything that we did and built and wrote and thought and discovered will be forgotten and all of this will have been for naught. Maybe that time is coming soon a nd maybe it is millions of years away, but even if we survive the collapse of our sun, we will not survive forever. There was time before organisms experienced consciousness, and there will be time after. And if the inevitability of human oblivion worries you, I encourage you to ignore it. God knows that's what everyone else does."

"I fear oblivion. I fear it like the proverbial blind man whos afraid of the dark." -Augustus Waters

Sniper Oblivion

Term used to describe snipers on Modern Warfare 2 completely unaware of nearby enemies, usually due to the fact that they are extremely hardscoping and unable to see peripherals. Sniper Oblivion is usually noticed by other team mates in Search and Destroy after one is knifed and the sniper offers no support.

Bad Kid 1: (Enters death lobby) DAMMIT that Marathon/Lightweight douchebag knifed me again, I hope Jess gets him.

Jess: (enters death lobby) aww man. Where'd he come from?

Bad Kid 2: *sighs* Sniper Oblivion dude...
