What percentage is a woo woo?

Could you please clarify the meaning of "woo woo" in the context of cryptocurrency and finance? Is it a slang term for a specific percentage, a reference to a certain market behavior, or perhaps a colloquial expression unrelated to the industry? I'm unfamiliar with this term and would appreciate a concise yet comprehensive explanation of its usage and relevance to our field. Thank you for your assistance in clarifying this matter.
