from your examples..
"Finna" as in PREPARING to do something soon
"Finnda" as in GOING to do something at a point later.
This is what I figured but when I asked some people who were using it, they couldn't tell me?!? I can understand using "Fix'in" in the South but this is NY? I also was asked for a "case quarter" which I responded "No" but have no clue what that is either.
STAY POSITIVE!!!!!!!!!!!!!!!!!
