slow-cooked corn chili
It's when you take a shit and find whole bits of corn staring back at you. An especially chuncky turd filled with corn -- in theory, slow-cooked XXX chili could be replaced where XXX = peanuts, twizzlers, peas, etc.
After drinking 13 PBR's, I tried pushing a fart out but instead got a load of slow-cooked corn chili in my underwear.
