The online term "two-door refrigerator" is usually used to describe the male characters in Korean cartoons. These characters are named for their broad shoulders, relatively small heads and similar body proportions. This metaphor emphasizes the height and strength of these characters, and is sometimes used to mock the exaggerated painting style with small heads and wide shoulders. In Korean culture, this figure is regarded as an ideal appearance standard, so "two-door refrigerator" is sometimes regarded as the pursuit goal of Korean men. In addition, the word can also be used to describe men or women who develop shoulder width and back spread through exercise, and they show good posture.
