What's with all the goofiness in this game?

When i saw this i was like… the hell? I thought it was cool that the game avoided this but… it eventually caught up.
Then we got the dude-bros with the high five and whoop whoop from Arsenio Hall.
And call outs saying they got a head shot… why do i need to know some one got a head shot?
At least with the “snipes” comment there is some info that you can use in some way.

They need to leave this stuff to the Grunts.

It’s an assassination?
