It’s probably a reference to the S E Hinton book The outsiders or the Robert Frost poem quoted in the book/movie “Nothing Good Can Stay”
Gold that is not good
Nature’s first green is gold,
Her hardest hue to hold.
Her early leaf’s a flower;
But only so an hour.
Then leaf subsides to leaf.
So Eden sank to grief,
So dawn goes down to day.
Nothing gold can stay.
