Okay, Dear, Ina.......please don't laugh at me for this, now........but when I kept repeating your "mystery words" to myself, what came to my mind was parts of an old (1950's) Hawaiian folk song, part of a Guy Lombardo Hawaiian record album that my mom and daddy used to play.
It had lots of the old favorites, like "Aloha Oe", and some of the beautiful ones; but of course the one that stuck in my little girl's mind was one called "My Little Grass Shack".
In the song, which was meant to be sung by some homesick Hawaiian , he sang about his home and the islands, " where the --(long unpronounceable words)-- goes swimming by" .
The strange words in the song are at least somewhat similar sounding to the ones you told us about.
Unfortunately , even YouTube could not come up with the Guy Lombardo rendition of the song. I chose this version, not because of the singing; but because she does a great job of pronouncing all of the Hawaiian words in the song.
Listen to it carefully, and when she gets to the part about the (whatever) swimming by; see if it sounds like your mystery words to you.
If not........I tried.
