Cover art for Stallion lyrics by Sunset Rubdown

In the book The Outsiders there is a really famous line that says "stay gold, pony boy"

I see that maybe he was trying to 'stay gold' off his life to-do list to look at it specifically. He already grew up though, so he is now a stallion instead of a pony boy and he doesn't believe in the same ideals as before.
