DESDE I TIEMPON MAGALLANES!
Magallanes is the Spanish / Chamorro version of a name we all know well, Magellan.
Ferdinand poked his nose around the Marianas in the year 1521.
That's a long time ago.
So it was an expression in years past to say, "Desde i tiempon Magallanes!" to mean it's been a long, long time since whatever.
Literally, it means "Since the time of Magellan!"
I heard this expression just the other day when I was thanking some people for taking me and a friend to a swimming spot. They, in turn, actually thanked me for asking them to escort us to that spot, for it had been a long time since they had gone there. The lady said, "Desde i tiempon Magallanes!"
The double L in Magallanes is pronounced like a Y in Spanish, and like a DZ in Chamorro. Like Acfalle and Quintanilla. MA - GA - DZA - NES.
