A term first used on the Chappelles Show, on the "Mad Real World" skit. It decribes a situation in which individuals(not neccesarily any particular race) are behaving in a loud, crazy, sometimes violent manner. Such behavior is usually drug or alchohol induced.
Mike: "Hey Vince! After we slam these beers Im bout to knock that nigga out, and leave the club with his girl."
Vince: "Niggas is wilin'!"
This term is actually contradictory. It confirms that the person does indeed have HIV, contracted by blood transfusion or sexual contact with a sambo/coon. This disease leads to BLAIDS, which is black AIDS. It not only kills you, but steals your money and property as it does so.
