Get the Black-Out mug.
A late-stage phase of niggarosity in which an individual of non-African descent is so overwhelmed by the desire to engage in the cultural choices, societal behaviors, and core conducts of African-Americans, that they subconsciously adopt such mannerisms, usually to the chagrin of true African-Americans, who tend to view such individuals as utter buffoons, and who are completely staggered by such behavior. There is no known cure.

When a person gets a tourettes-like tendancy to say "Dayum!", "Shi-it!" and "Dat is WACK!" out of the blue, which is coupled with a craving for fried chicken, watermelon, or malt liquor. While experiencing a black out, all or most sentences will end with "motherfucker!"

In some extreme cases, the suffering party's skin may become significantly darker during this time.
