To help me understand what you're looking for, could you please provide more context? For example:
* Where did you encounter this word? (e.g., a book, a website, a conversation)
* What was the context surrounding the word? (e.g., what was being discussed?)
* Do you have any idea what language it might be from?
With more information, I might be able to figure out what "ocomogosiay" means!
