When I hear "chuffed" I think of how cockatoos put their feathers up over their lower beak when they're pleased with themselves (or sleepy); you can see Ngarritj and the others do this several times in that clip.
Well done .. although Yolngu has to be the easiest (and not that easy at all) to pick up rough translations on the web - there are many* that don't feature at all given they're oral with no alphabet, phonetics came late with the missionairies and linguists.
As the spelling "Yolŋu" attests, I guess IPA goes a long way towards allowing dictionaries for non-alphabetic languages. (It's well known that the polynesians lost the t/k distinction moving eastward, in between settling Tahiti and Hawai'i, but at one point it occurred to me that missionaries moving westward might also have gotten better at transcription?)
When I was into The Expanse's Lang Belta (a creole), I was following BBC Pidgin: https://www.bbc.com/pidgin to get some feel for the possible antecedents. (UK:"Most read" = Pidgin:"De one we dem de read well well") Just to complicate things, what gets called "Hawai'ian Pidgin" is actually a creole as well, eg: https://www.youtube.com/watch?v=R15IQAVT7Rg (Is the use of "Aunty" parallel between this and Oz cultures?)
I'm just a fan. Thanks very much for the pointers into a new set of cultures* for me; up until now I've been enjoying cultural appropriations (consider the platypus!) in the other direction, eg polka acca dacca: https://www.youtube.com/watch?v=n_gtGfAail4 (and songlines I only discovered today while trying to figure out what the Oz equivalent of the https://en.wikipedia.org/wiki/Inuksuk might be)
* so far these mobs have been using a basketball court as an impromptu community centre/dance floor, which I guess they share even with very highly produced numbers, like "Baby One More Time"? As basketball had yet to be invented, earlier germans contented themselves with dancing around lime trees: https://de.wikipedia.org/wiki/Tanzlinde
(the hopping in the aboriginal ceremonies reminded me of the very avian caucasian dances: https://www.youtube.com/watch?v=vJ6FzIgKWl0 ; compare https://www.youtube.com/watch?v=eJHCaahJ4pY&t=52s )
