What is Hawaiian slang for brother?

There isn't one specific Hawaiian slang word for "brother" like there might be in other languages. However, depending on the context and closeness of the relationship, you could use a few different words or phrases:

* "Brah": This is a common Hawaiian slang term for "brother" or "friend", often used in a casual and friendly way.

* "Cuz": Short for "cousin", this is another common slang term that can be used for brothers, especially if they're close in age or have a close relationship.

* "Kane": This word literally means "male", but it can also be used to refer to a brother or a male friend.

* "E ke Akua": This phrase literally means "by God", but it can also be used as an expression of affection and closeness, similar to saying "brother from another mother" in English.

It's important to note that the best way to address someone will depend on the specific relationship and context. Using "Brah" with a stranger would be inappropriate, for example, but it's perfectly acceptable between close friends.
