"Partially derived from the word "knocker", and almost acts as a possible subsitution for "nigger" but takes on a unique meaning that can only be understood by a "naca" himself
1. a real good buddy, or friend, who never lets you down.
2. a member of a tight group of friends that play it cool, and always know how to make things interesting." -Vile Scamp
A naca will always share weed with another naca, no matter how low their stash.
My naca, thank you for the great bud.
