It's a play on the wish in the book “The Outsiders” their quote is “Stay Golden Pony Boy”

They reference Robert Frosts poem nothing gold can stay:

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.
