It's possible that:
* It's a misspelling: Check for typos or variations. Maybe you meant a similar word like "Minooka" (a town in Illinois, USA).
* It's a regional or niche term: If you heard it in a specific context, like a particular field or region, it might have a local meaning.
* It's a personal name or made-up word: Without further context, it's hard to determine its meaning.
To help me understand, please provide more information:
* Where did you hear or see "minoaka"?
* What was the context?
* Do you remember any other details?
With more information, I can give you a more accurate answer.
