Why does the lion club stink?

The phrase "lion club stink" could refer to a variety of contexts, but if you're referring to the odor associated with actual lions, it may be due to their habitat and diet, which can produce strong smells. In a metaphorical sense, if "lion club" refers to a group or organization, the "stink" might imply negative perceptions or issues within that group, such as poor management or unresolved conflicts. Clarifying the context would help provide a more specific answer.
