ULTRAKILL

MANKIND IS DEAD.
BLOOD IS FUEL.
HELL IS FULL.

an early access boomer shooter on steam, also called sex 2
it's if doom, quake and devil may cry had an orgy on a couch and god sprinkled 20 tons of cocaine on them

my point is that it's a good game, go buy it, it's 20 bucks
even though it seems expensive and still in early access it has a shitload of content

1: hey you heard of that early access game called ULTRAKILL?
2: yea, Civvie 11 reviewed it, and also remember when he said "BLOOD IS FUEL, FOR MY COCK"?
1: yea that was pretty funny

you shall ultrakill thyself, immediately 

A meme reference to the game "Ultrakill", where a character named Minos Prime says that you should commit die.
This line is not actually said in-game.

You shall ultrakill thyself, immediately, machine!
