It’s hard to tell…
It doesn’t really symbolize the mouth. It’s more like a monster. The name of the monster is undefined, it always remains a secret. A person commented something that the lines are very shaky.
The process of drawing is located in the video. You can call this a “Sour Lip”, because it is used to refer a lip that contains a lime inside.
