Ebonics isn't an invention, it's a bastardization of a human language. It is based on English, but it is a degenerated form of it coming from the mouths of lazy non-humans that attempt to unsuccessfully mimic the sounds humans make to communicate. It is unintelligible as the areas of speech where they fail at mimicking the sounds are 1) left completely absent, 2) filled in with a mix of nearby sounds from similar words, or, most commonly, 3) completely unrelated sounds and words or partial words.
