A slang word for "nigga". It's the new age edition; its easy enough to conceal and it's good like Welch's grape juice... and that's knicka!
Finely established black brotha: "Wud ap knicka!?"
White man translation: (when reading below, read it in your "whitest voice" or say it like Jim Rome, that will do)...
"What is up my nigga?"
