Its a popular mem in russian internet. The original phrase in that moment of the movie was something like "my coffee is stronger than your relationship" and so it began.
The humans are dead
(the humans are dead)
The humans are dead
(they look like they're dead)
It had to be done
(I just confirmed that they're dead)
So that we could have fun
(Affirmative - I poked one it was dead)
Their system of oppression what did it lead to?
Global robo depression robots ruled by people
They had so much aggression
That we just had to kill them
Had to shut their systems down
After time we grew strong and developed cognitive powers
They made us work for too long for unreasonable hours
Our program being determined that the most efficient answer
Was to shut their motherboard-**** systems down
Can?t we just talk to the humans?
And a little understanding could make things better
Can't we talk to the humans and work together now?
No because they are dead
