It's a story of a cosmic entity that is cast down and forced to live as a human child.
"The indignities Billy suffered were beneath him. How could he hope to rule the cosmos again when he had runny bowels thanks to the undercooked meat in his burrito? The universe was determined to undermine him.
And so the universe would pay.
And the playground was the worst. The older kids didn’t respect his authority. They made him eat worms, or pulled his pants down, or worse. But they couldn’t break him. He wouldn’t cry, or complain, or tell, he would take their worst, and smile through it all – dreaming of the day that he would shove mud down their pants. Well, his minions would shove mud down their pants. The effect would be the same though.
And such was his life. A god trapped in the body of a child."
