ㅈㄹㅅㅎ
I don't even know what this means.
but it's kind of a word made up of each consanant of letters.
Do you know what 감사 means? I bet you know it already.
People tend to write ㄱㅅ instead of 감사 especially in mobile phone as you do in english like 'laugh out loud' as 'LOL'
As I said I don't know what ㅈㄹㅅㅎ is.
hope you enjoy learning Korean.
