When a black female proceeds to laugh, cackle, and screech at the same time- signalling an impending attack. It is often done by younger black women, but older ones may also do this if provoked.
Black woman: *screeches incredibly loudly to signify attack*
White people: OH SHIT RUN, SHE JUST DID THE BLACK WOMAN ATTACK SCREECH!
