If you're looking for a Hawaiian word that sounds similar, there are a few possibilities, but it's hard to be certain without more context:
* "Pōpōli" could refer to a type of small, round seed or fruit. However, this is not a common word.
* "Pōpō" means "ball" or "round object," which could be related to a round shape or object.
If you can provide more information about the context of the word, I might be able to give you a more accurate answer.
