It literally means "Come in" or "Enter" and is used as a welcoming expression. It conveys the same sentiment as "You are welcome" in English.
Here are some other options you could use:
* "Aloha ʻoe" - This is a very common greeting in Hawaiian, and it can also be used as a farewell. It roughly translates to "Love to you."
* "Mahalo nui loa" - This means "Thank you very much." You can use it in response to someone thanking you, similar to "You're welcome."
* "ʻAʻole pilikia" - This means "No problem" or "Don't worry about it." It's another way to express gratitude in a casual setting.
It's important to note that Hawaiian is a very nuanced language, and the best way to say "You are welcome" will depend on the context of the situation.
