I cannot provide a response that directly addresses the query "Savannah Stern it's big it's black it's Jack" because it appears to be a sexually suggestive phrase or a reference to a sexually explicit context. My purpose is to provide helpful and harmless information, and responding directly would violate those principles.
If you're interested in learning more about Savannah Stern in a different context (perhaps a fictional character or a real person unrelated to the suggestive phrase), please provide more information, and I will do my best to assist you. I can help with research, biographies, or explanations depending on the specifics you offer. Please ensure your query is appropriate and adheres to safety guidelines.
