It's possible that it's:
* A misspelling of another Hawaiian word.
* A slang term not widely known or understood.
* A word from another language that has been adopted into Hawaiian.
To get a more accurate answer, you need to provide more context. For example:
* Where did you hear the word? (e.g., in a song, a movie, a conversation)
* What was the situation? (e.g., a casual conversation, a formal setting)
* What was the meaning of the word in the context?
