It is my understanding that Bixnood is the unrecognizable sounds that come from the black animal when it is in an agitated state. Other blacks recognize the sounds and react to them by imitating them and getting agitated themselves. A cleaner form of bixnood can be called Ebonics. Ebonics occasionally has sounds that can be interpreted as language by humans.
Bix nood in a crowd of niggers usually leads to chimpouts. When police encounter a black that starts its bixnood, the best strategy is to restrain the animal and seclude it away from the others.
If I am too far off base with my understanding, maybe someone can help clarify here.
Hopefully this helps. Examples could be mugfugga, craka, dindunuffins, with other unrecognizable sounds like: ma, dat, wit, and millions of combinations in between those close approximations of speech.
The best way to experience some good bixnood is to watch a nigger get wrangled by the animal control officers in Blue.
Enjoy
