Barfing Floof (floofinition) – Annual event among pets focused on art, self-expression, and self-reliance, highlighted by a period when they all start bringing up hairballs.

In use: “The annual Barfing Floof always troubled Michael. First only one cat participated but he apparently convinced the others that they should participate. At least it was just hairballs. Finely formed hairballs. He wondered how they did that. And why.”
