Hawaiian Pidgin is a way of talking that some people use in Hawaii. It's kind of like a mix of different languages, such as English, Hawaiian, and other languages that people who live in Hawaii might speak.
Let's say you want to ask someone what they're doing. In English, you might say, "What are you doing?" In Hawaiian Pidgin, you might say, "Wassup, brah? You doing?"
It might sound a little confusing at first, but once you get used to hearing it, it can be really fun to use. A lot of people who grew up in Hawaii speak Pidgin naturally, so if you ever visit or move to Hawaii, you might hear it a lot!
