Anyone who has spent any time at all in Hawai'i is familiar with at least a few words of Hawaiian pidgin, even if they'd never attempt to speak it, because they are so woven into the everyday culture.
Here are a few that come to my mind as fairly widely understood by residents. I'm sure there are others...
Manapua - pork bun with BBQ pork or other filling; pidgin adaption of Hawiian loanwords mea ono pua 'a, meaning delicious pork pastry
Slippahs - rubber sandals; known on mainland as flip-flops
Howzit? - How are you? Casual greeting
Da kine - the kind, the ultimate Hawaiian superlative. "Those are da kine manapuas!"
Broke da mout - broke the mouth; very delicious.
Ono grinds - delicious food; "Ken's shrimp truck has ono grinds."
Kaukau - food, or to eat; adapted from Chinese "chow chow." "I'm ready for kaukau."
Chicken skin - goose pimples
Skosh - a little bit; adapted from Japanese loanword sukoshi. "This poke needs a skosh more salt."
Braddah, sistah - brother, sister
Brah - Bro', or mainland "dude"
Cuz' - cousin; used in the loosest possible sense in Hawai'i because "everybody is family," a friend
Uncle, Aunty - also used in the loosest sense as a respectful term for an elder; Like "sir," and "ma'am" in southern states.
Moke - a big, tough Polynesian man; like "redneck" it can be used as a pejorative, or as a term of self-pride.
Tita - a big, tough Polynesian woman; see above
