What is so it goes meaning?

"So it goes" is a phrase made popular by Kurt Vonnegut in his novel "Slaughterhouse-Five". It is used throughout the book as a memento mori, a reminder of the inevitability of death and the impermanence of life. The phrase is often used after a death or a tragic event, suggesting that this is just how life goes on despite the pain and suffering. It has since become a cultural meme, used to express resignation toward the futility of life, human trauma and grief, and the ultimate mystery of existence.
