Black
slang for "holler" - used as an exclamation of an understood, universal awareness, affirmation, arrival or recognition of a particular
reality or a
person or both.
(A student gives a speech at graduation where she references an inside,
maybe taboo, experience that all students are aware of. When other students begin to call out a key
word, acknowledging the fact to her in
support, she laughs and echoes back... "Hollah!"
