A person (typically male, can
be black but not always) that is
deserving of high regard and/or fear in some way, due to accomplishment, reputation,
specialized skills, or a combination of everything stated. When spoken of, noticeable emphasis in the sentence is usually on the word 'that' when used to describe 'that nigga.'
If you want to get something done, you can go to anybody. But if you want it done right,
I'm that nigga.
Oh shit, the one with the 22 inch chrome on the caddy? He's THAT nigga?
"Alligator seats with the head in the inside
Swine on the dash,
G-wagon is So Fly
Number one don't tangle and twist it
When it come to these cars I am that nigga"

Still Fly"
