Yaminjeongeum (Korean: 야민정음; Hanja: 野民正音) is a South Korean Internet meme which disassembles Hangul characters of a word and replaces them with others which appear similar to the correct form.
For example, daejang (대장, "chief") is changed into meojang (머장), since dae (대) resembles meo (머).
The name Yaminjeongeum is a blend of Hunminjeongeum and Yagael (야갤); Yagael is short for Gungnae Yagu Gallery (국내야구 갤러리; 國內野球 갤러리), the domestic baseball league section of DC Inside.
There are various ways to convert a word into yaminjeongeum: just replacing its consonants or vowels, rotating it, compacting it, or even using Latin alphabet.
[9] Critics state that the meme destroys Hangul and is a type of verbal violence, but supporters state that it is just a part of culture and improves the Korean language.
