Here's why it's difficult to translate:
* "Ehu" is not a common Hawaiian word. It might be a misspelling of a different word, or a made-up term.
* "Girl" has different meanings in Hawaiian. The most common translations for "girl" are "kaikamahine" (young girl), "wahine" (woman), or "keiki wahine" (child girl).
To help find a better translation, I need more context. Please provide more information about what you're looking for, such as:
* The context of the phrase: Where did you hear it? Was it in a song, a movie, or a conversation?
* The intended meaning: What kind of girl are you referring to? Is it a specific type of girl, or just a general term?
* What are you trying to achieve with the translation? Are you looking for a literal translation, or a more poetic interpretation?
