The word finna came from the word "fixing to" but it is used a lot of the time by
people who are
black and it means "going to." An easier way is also just "bouta"
like "about to." Ex. "I'm finna go get hype" can also be replaced with "I'm bouta go get hype."
Modern use--"yo Josh I'm finna
go get
hype at the club, wanna come?"
Meaning--"hey Josh, I'm about to go get
hype at the club, wanna come?"
about to bouta and going to. All work
