What does FN stand for?

{Intro}
{Uh, uh, uh uh,}
{Uh, uh, uh uh,}
{Uh, uh, uh uh,}
{Uh, uh, uh uh,}

[Hook]
Fuck the internet talk i don't fight i'mma up it
Why you riding my dick, moving like a puppet
Fadeaway, Luka, im scorin a bucket
They got shit to say then tell em to stuff it

I don't wanna hear it
Never cared 'bout appearance
Shit ain't never that serious
U think u that nigga u ain't there yet u keep lackin experience

They keep saying they ruling the underground
I swear these niggas delirious
100 rounds fired with my cadence
They cannot copy my flow it's mysterious

[Verse]
We ain't up yet but bitch im go on somе VIP shit
TEC on my hip loaded if i up it yo ass finna eat shit
On the grind for C.H.E.C.Ks
Mask on no facе no case
Blasting, crackin 4s like a vase
And im still saying free tay k

FN on a Fuck Nigga, talk shit, nigga we gon let it spray
4 deep on your block, talking shit on twitter, this internet shit don't play
The situation where you niggas is better than me is really really far away
I let my bitches slay, yuh

[Bridge]
{Uh, uh, uh uh,}

{Uh, uh, uh uh,}
