NBKFA 

1: A cheat code for the game DUSK, published by NewBlood.

Typing said cheat code at any time while in game will give you all the keys, all the weapons, and max ammo.

It is assumed that NBKFA stands for: NewBlood, Keys, Full Arsenal/Ammo

Obviously a reference to IDKFA

2: NoBody Knows Fucking Anything

1: "hey dude, if you're having trouble with a level in DUSK, try entering NBKFA!"

2: *in reply to some random tweet about people being dumb* "Ugh, NBKFA, right guys?"

NBFAV 

NBFAV is the abbreviation of the phrase "Not Bad For A Village". It is an expression that describes something that is decent. It shows satisfaction with a thing of which you had low expectations.

For example, if you found a videogame pretty good despite it being expected to be mediocre, you would say:

That videogame is NBFAV
