The potato is a prime example of 'comfort food,' giving a warm and cozy feeling. It fits well when talking about comforting home-cooked meals like Korea's 'gamja-jeon' (potato pancake) or 'gamja-tang' (pork bone soup).

In English-speaking countries, a lazy person who just lies on the sofa watching TV is called a 'couch potato.' In Korea, it's more often used with a positive and cute meaning, such as a nickname for chubby and cute animals or people.
