Essential Korean

Like I guess some other foreigners, I was sometimes puzzled to read some "expressions" on Facebook or on SMS. Things such as "kkkk" or "ㅋㅋㅋ" (which is actually the same, anyway) made me think "WTF is going on!". Google Translator is not very helpful, just translating it as "blah blah blah", so I decided to do some little research and... tada! Here are the main "abbreviated expressions" Koreans use in their short messages!

ㅋㅋㅋㅋ/ㅋㄷㅋㄷ/ㅎㅎㅎ = kkkkkk. lol/rofl/lmfao depending on how many ㅋ
(in sc) ㅎ = help
ㅈㅈ = gg
ㄱㄱ = gogo
ㄴㄴ = nono
ㅠㅠ = qq
ㅡㅡ= -__-
ㄱㄳ = gogosing
ㄹㄷ = ready
ㄹㄹ = rm (in sc)
ㄴㅅ / 낚= rj (in sc)
ㅂ = back (in sc) (get back) (dont go)
ㅎㅇ/ㅎ2 = hi
ㅎㅇㅇ/ㅎ2ㅇ = hiyo
ㅂ2ㅂ2 /ㅃㅃ= byebye
ㅇㅋ = ok
ㅇㅇ = yea yea
ㄱㄷ = wait a sec
ㅉㅉ = tsk tsk (kicking your tougue sound)
ㄷㅊ = stfu
ㅅㅂ/18 = shit (mostly as in aww shit)
ㅄ = retard
ㅅㅂㄹㅁ / ㅅㅂㄴㅇ= shitface/fuckface/fag/fucktard/dooshbag/fucker, etc.. kinda reminds me of 섊 (ole skoo way to say it rofl)
ㅈㅅ = my bad
ㄳ= ty
ㅅㄱ = (after you meet back in channel kinda like gg (in sc only)) other ways to use but hard to explain
ㄲㅈ = gtfo
ㅁㅊ = fucking...
ㅎㄷㄷ = gee (same key input too rofl)
82 = hurry tfu
