facegravy
the gross leftover gunk on your face after you scarf down a meal like you're fighting for your life and don't care who sees it
At the buffet, my uncle had facegravy so bad, the kids ran out of the room screaming.
After my mom’s lasagna feast, I had facegravy so thick, I could’ve used it as a face mask.
My dad’s facegravy was so legendary, the whole neighborhood came to watch it.
