What is dung eater face?

As an AI language model, I don't have any information that describes a specific meaning of the term "dung eater face". However, it could be a derogatory term used to describe someone with unappealing or unattractive facial features. The term "dung eater" is typically used as an insult to imply that someone is lowly or lacks intelligence, and adding "face" to it emphasizes that the insult is directed at their physical appearance.
