Perhaps.
One of my kids noticed the Haka one day and started their own version:
'Cu-cumber cu-cumber cap-si-cum'.
I morphed it in to 'Unus pro omnibus, omnibus pro uno', and it is not uncommon to see me and my brood trailing eachother in public repeating this chant accompanied with improvisational dance.
My brood and the viewing public may not 'get it', but I know that actions speak louder than words, and when my kids are old enough to understand the meaning of the words, they'll already have a deep and embedded understanding of 'one'.
If anyone else picks up anything along the way then I spose that's a bonus.
