Definition & Meaning of "crazy man in the bottle"in English

What does "crazy man in the bottle" mean in Nigerian slang?

In Nigerian slang, "crazy man in the bottle" refers to illicitly brewed alcohol or strong homemade spirits, often of questionable quality or potency. It is used in informal Nigerian English and street slang when talking about cheap or unregulated alcoholic drinks.
