Notes on Usage

• "Ăn bùn" is a highly specific compound term. It is not a common colloquial phrase and should not be confused with literal, non-scientific interpretations of "eating mud."
• In standard language, describing a person or animal accidentally or strangely eating mud would typically use a different structure, such as "ăn phải bùn" (to eat mud by accident).
