Inugui refers that 'people eat like a dog' in Japanese food culture and means that people move their faces (mouths) closer to the meal on the table in an extreme stooped position, and eat them as if they put their heads into the food.
犬食い（いぬぐい）とは、日本の食文化の上で「犬のように食事を食べる」状態を指し、テーブル上にある食器に盛られた料理に、極端な前屈姿勢で顔（口）を突っ込まんばかりに近づけて食べること。
