Booted up my PC, 'cause I need, need
To get that Fortnite battle pass

FNBN 

An acronym denoting "For Nerds By Nerds." Used in reference to internet memes or supposedly unbiased internet articles that are obviously written for and by nerds, g33ks, 1337s, hax00rz, or any of the C++ speaking elite social class.

That ridiculously huge and well annotated Wikipedia article on the Star Wars Kid is obviously FNBN.
