What is the meaning of this "ㅋㅋㅋㅋㅋㅋ"?

[trutherous]

It means 'lol' or 'hahaha' --if you can imagine a snickering sound like 'ki ki ki' ㅋㅋㅋ ㅋㅋㅋ

If you see, "ㅋㅋㅋ" or "ㅎㅎㅎ", those mean "hahaha~~^^"
Many Korean people are too lazy to properly type "킥킥킥" or "하하하"; that's why those two "ㅋㅋㅋ" and "ㅎㅎㅎ" are used.
cheers,
