mutupo
in slang means very expensive wine (waini) or liquor (chapomba) that an average person can't afford to purchase on a regular basis because this will turn their financial health upside down completely.
Note: The formal meaning of mutupo in chiShona language is "totem" but in this case, I am talking about slang as aforementioned above. The opposite of mutupo is something like masese (sorghum beer), brown bottle (lager, ale, and stout beer), musombodhiya (moonshine), etc.
