What is ㅋㅋ or ㅎㅎ? July 30, 2016September 30, 2018 ~ funkorean4u ~ Leave a comment What is ㅋㅋ in Korean? It is a chatting word which means “laugh” or “funny”. One of the laughing sounds in Korean is 크크, so we just write that without vowels. There is also ㅎㅎ, which is 하하. So if you see something funny, you can leave ㅋㅋ or ㅎㅎ.
