facegravy
the slimy mess left in the corner of your mouth after you stuff your face like a greedy pig and don't care who sees it
My cousin left facegravy after eating three burgers and a milkshake. It looked like he had a leaky faucet in his mouth.
At the family reunion, my aunt’s facegravy was so thick, my cousin took a picture of it and posted it on Instagram.
After the pizza party, my brother had facegravy so big, it looked like he was wearing a sauce mustache.
