Later in the day, I was relating my meal to someone, and described it as "halfway to a slinger". I thought everyone knew what a slinger was, but from the blank look on their face I knew they had no idea what I was talking about. I did some Wikipedia research, and learned:
The Slinger is a Midwestern diner specialty typically consisting of two eggs, hash browns, and a hamburger patty (or any other meat) all covered in chili (with or without beans) and generously topped with cheese (cheddar or American) and onions. The eggs can be any style. The Slinger is considered to be a St. Louis late-night culinary original.
