Apanua, hapanoa - a rite of passage for Hawaiian children entering puberty.
Haole does mean White Man, but used to refer to any foreigner.
Poke - A raw fish salad served as an appetizer in Hawaiian cuisine.
"Only haoles pronounce it Hawaii, Butters" - Stephen then pronounces it like haoles do for the rest of the episode, lol.
Keiki - little one, kid, child.
To go native in Hawaii is to make a home there and come back to it at least once a year.
Saimin is a Hawaiian soup, saidon is a combination of saimin and Japanese udon (which is also a soup).
Mahalo - thank you. So everyone is carrying a Thank You Rewards card.
Coco Palms - closed for 20 years due to Hurricane Iniki, and there are no plans to reopen it.
Kapu - forbidden or sacred, related to taboo.
Heh, blankets and cocoa. Or maybe those Hawaiian tourists are drinking chi-chi. Who knows? lol
An Easter Island head in Hawaii?
"Trial by opaeka'a." - if Kenny survives the Opaeka'a Falls, he'll be accepted as a "native" along with Butters. Of course, if he had stayed on the paddle board, he would also be accepted.
The Fern Grotto
This episode shows us that Trey has a home in Kapaa, Kaua'i, and about life there.
So Butters had a thing for Jennifer Lopez and was very jealous of Ben Affleck for having her as his girl. Once he learned that Ben had married Jennifer Gardner some time ago, his anger vanished. It seems to have been the source of his disruptive behavior at school, and for that he wants to apologize to his classmates.
hapa means half, noa (from kunoa) means free, so hapa noa is "half free," which is what a person entering puberty is, heh. Once he reaches adulthood, he's fully free.
