Notes:
1. Mahalo is virtually limited to Hawaii. Though this is not a common word to hear in mainland America, many Americans know this word because it has a small but notable presence in the media.
2. Mahalo can be both casual and polite. It's considered acceptable to say mahalo in place of thank you to your superior like a teacher or a boss in Hawaii.

*Mucho is Spanish for many. So "mucho mahalo" would mean "many thanks." The majority of Americans know the word mucho due to the Hispanic presence in the country and it's often joined with other words.
