Jjokbari

Jjokbari (쪽발이, borrowed into Japanese as チョッパリ, romaji choppari) is a Korean language ethnic slur which may refer to Japanese citizens or people of Japanese ancestry. A variation on the slur, ban-jjokbari, meaning literally "half-jjokbari", has been used to refer to mixed Japanese-Korean people, as well as Koreans in Japan who returned to the peninsula.

According to one survey, it was South Korea's second-most commonly used slur against Japanese people, ahead of wae-nom and behind ilbon-nom.

The term has also been borrowed into Japanese language spoken by ethnic Koreans in Japan, where it is rendered Choppari.

Origin
The original meaning is "A cloven foot". Jjok means a "piece" and bal means "feet" in Korean, and when combined it roughly translates to "split feet" or "cloven hoof". This etymology refers to the fact that the Japanese wore geta, a traditional Japanese wooden sandal, which separates the big toe from the others.

Unlike Korean-style straw shoes which completely cover the foot, Japanese-style straw shoes and wooden geta consist of only a sole and straps to bind it to the sole of the foot. This leaves the rest of the foot exposed, including the "split" between the toes. Koreans thought of Japanese shoes as incomplete compared to their own, and the visible split as a distinctive enough trait to inspire an ethnic slur.

Ban-jjokbari
The form ban-jjokbari (literally, "half jjokbari") originated as a derogatory reference to Japanized Koreans during the Japanese colonial period in Korea; later, it came to be used to refer to Japanese with Korean ancestry, as well as Koreans in Japan who returned to the peninsula in both North and South Korea.

The Japanized pronunciation of this form, ban-choppari, is also widely used by Koreans in Japan in a similar manner.
