From a comic by the cartoonist A. Wyatt Mann, which depicts a black man speaking in gibberish. It was later reuploaded by users of the 4chan image board /b/. It has no known discernible etymological root.

There's an old A Wyatt Mann cartoon with an incredibly racist (obviously, given the author) depiction of a black dude saying gibberish into his cell phone (the words "bix nood" being part of this gibberish), and it became a meme.

Here he is reporting the story to a cop
