A popular breakfast food item, especially in the southern U.S. Technically known as "Sausage Gravy and Biscuits." Someone who doesn't appreciate the finer things probably decided that it looked like something the "cat yacked-up" on a plate.
"I'm so hungry I could eat the north end out of a southbound skunk! Bring me full order of cat yack and a cuppa joe."
