Kuchisabishii

Kuchisabishii literally means 口 kuchi- mouth and　寂しい sabishii- lonely, “lonely mouth”, but translates to “longing to have or put something in one’s mouth”. I prefer the more creative “eating when you are not hungry because your mouth is lonely”. https://blossomkitty.com/2020/04/17/uniquely-japanese-kuchisabishii-%E5%8F%A3%E5%AF%82%E3%81%97%E3%81%84/
