situational obliviousness 

The opposite of situational awareness. Having no clue what's going on around you. Straight-line thinking - aware of your world and its goings ons only.

Sheila almost ran over a biker because of her situational obliviousness.

Mike called the boss a stuck up turd when he was right behind him. That situational obliviousness has him working the weekend.

Oblivion 

The fourth game in the Elder Scrolls series, and arguably the best game in the history of mankind. By purchasing this game, you have sold your soul to Bethesda Softworks--which is a pretty even trade-off, actually. Once you start this game--assuming your computer/Xbox 360 doesn't burst into flames of righteous fury due to it's lack of uberness-- you will not be seeing the sun for a while.

Side effects include: Weight loss, paleness of skin, weight gain, reluctance to leave your chair, death, peeing in a bottle, ordering pizza every night because you can't stop playing long enough to make some food, loss of the ability to distinguish between fantasy and reality

Because of Oblivion, I no longer have a soul!

God bless BethSoft for this gift to man.

Oblivion 

Something inevitable. We will all die one day and there will be no one to remember us. In a book, a man was afraid of oblivion, that no one would remember him when he dies. It is the state of being forgotten.

Augustus Waters is afraid of oblivion.

Captain Oblivious

A person, often otherwise intelligent, who routinely exhibits a comical lack of understanding in social situations.

Such a person is typically well-known for their repeated well-meaning tactlessness, failure to notice romantic overtures, tendency to walk into doorknobs and general forgetfulness.

"Blunt!"
"Cheerful!"
"Clumsy!"
"Absentminded!"
"Negative square root of two!"

By your powers combined, I am... Captain Oblivious!

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
