Korean Texting Slang: ㅋㅋ, ㅎㅎ, ㅠㅠ, and Chat Abbreviations Explained

Korean text messages and group chats have their own style. Hangul consonants alone can express laughter, tears, and quick replies, and many long words get shortened. If you chat with Korean friends or read comments online, knowing this style will help you understand the mood and join in naturally.

Laughing and smiling

• ㅋㅋ: laughter, like "haha" or "lol." More ㅋ means more laughter.
• ㅎㅎ: a softer, friendlier laugh or smile, like "hehe."

• 진짜 웃겨요 ㅋㅋㅋ

  [jinjja utgyeoyo ㅋㅋㅋ]

  That's really funny lol

• 감사합니다 ㅎㅎ

  [gamsahamnida ㅎㅎ]

  Thank you hehe

ㅋ comes from the sound of laughter (크크), and ㅎ from 하하 or 흐흐. Many people use ㅎㅎ in polite messages because it feels gentle, while long strings of ㅋ are more casual.

One ㅋ or ten?

The number of ㅋ carries real meaning. A single ㅋ can feel dry or even sarcastic, as if you are not impressed. Two or three is a normal laugh, and a long string means you are genuinely cracking up.

• 너무 웃겨 ㅋㅋㅋㅋㅋㅋ

  [neomu utgyeo ㅋㅋㅋㅋㅋㅋ]

  That's hilarious LOL

Another friendly signal is ^^, a smiling face made from two carets. It is common even in polite messages, because it softens the tone without being too casual.

• 내일 뵙겠습니다 ^^

  [naeil boepgetseumnida ^^]

  See you tomorrow :) (polite)

Crying and sadness

ㅠㅠ and ㅜㅜ look like crying eyes with tears streaming down. They can express real sadness, sympathy, or playful disappointment.

• 오늘 못 가요 ㅠㅠ

  [oneul mot gayo ㅠㅠ]

  I can't go today :(

• 너무 피곤해요 ㅜㅜ

  [neomu pigonhaeyo ㅜㅜ]

  I'm so tired :(

Consonant abbreviations

Some common words are shortened to their first consonants. These are casual and best used with friends.

• ㅇㅇ: yes, yeah (from 응응)
• ㄴㄴ: no, nope (from 노노, "no no")
• ㄱㄱ: let's go (from 고고, "go go")
• ㅇㅋ: okay
• ㄱㅅ: thanks (from 감사)
• ㅈㅅ: sorry (from 죄송)
• ㅊㅋ: congrats (from 축하)

• ㅇㅋ 내일 봐!

  [(okay) naeil bwa]

  OK, see you tomorrow! (casual)

Decode new abbreviations yourself

Most of these codes follow one rule: keep only the first consonant of each syllable. 감사 becomes ㄱㅅ, and 죄송 becomes ㅈㅅ. Some follow the sound instead of the spelling. 축하 is pronounced chuka, so congratulations becomes ㅊㅋ rather than ㅊㅎ.

Here are more codes you will see often:

• ㅅㄱ: good work, take care (from 수고, common in games and casual chats)
• ㄷㄷ: shocked, scared, or impressed (from 덜덜, the sound of trembling)
• ㅇㅈ: agreed, facts (from 인정)
• ㄹㅇ: for real (from 리얼, "real")
• ㅂㅂ: bye-bye (from 바이바이)
• ㅎㅇ: hi (from 하이)

• 오늘 수고했어 ㅅㄱ

  [oneul sugohaesseo (sugo)]

  Good work today, take care

• ㅇㅈ 그 노래 진짜 좋아

  [(injeong) geu norae jinjja joa]

  Agreed, that song is really good

• ㅂㅂ 내일 봐

  [(baibai) naeil bwa]

  Bye, see you tomorrow

Shortened words

Koreans love to shorten longer words and phrases. Some are now so common that they appear in everyday speech too.

• 생일 선물 → 생선

  [saengil seonmul → saengseon]

  birthday present (playfully, since 생선 also means fish)

• 맛있어요 → 맛있당

  [masisseoyo → masitdang]

  delicious (cute, playful spelling)

• 아니요 → 아뇨

  [aniyo → anyo]

  no (common contraction)

Playful spellings like adding ㅇ to the end (맛있당, 고마웡) sound cute and friendly. Use them only with people you are close to.

More shortened words and cute replies

• 생축: happy birthday (from 생일 축하)
• 셀카: selfie (from "self camera")
• 꿀잼: super fun (꿀 means honey, 잼 comes from 재미, fun)
• 노잼: boring, not fun
• 반모: casual-speech mode (from 반말 모드)

• 생축! 행복한 하루 보내!

  [saengchuk haengbokan haru bonae]

  Happy birthday! Have a great day!

• 이 영화 꿀잼이야.

  [i yeonghwa kkuljaemiya]

  This movie is so much fun.

• 반모 하실래요?

  [banmo hasillaeyo]

  Shall we talk casually? (asked politely)

반모 하실래요? is a common way for people who met online to agree to drop polite speech. It is polite on purpose, because you are asking permission.

Yes has its own chat variations too. 넵 is a bright, eager yes, and 넹 and 웅 (from 응) sound cute and are best kept for friends.

• 넵, 알겠습니다!

  [nep algetseumnida]

  Yes, got it!

• 웅 나도

  [ung nado]

  Yeah, me too

Common chat expressions

• 대박

  [daebak]

  amazing, no way (reaction to big news)

• 헐

  [heol]

  whoa, what (surprise)

• 인정

  [injeong]

  agreed, true (literally "acknowledgment")

• 짱

  [jjang]

  the best, awesome

• 이 카페 진짜 대박이에요.

  [i kape jinjja daebagieyo]

  This café is really amazing.

A sample chat

Here is a short, made-up chat between two friends who just got concert tickets. Everything is casual 반말, which is natural between close friends.

• 오늘 콘서트 티켓 성공했어!!

  [oneul konseoteu tiket seonggonghaesseo]

  I got the concert tickets today!!

• 헐 대박 ㅊㅋㅊㅋ

  [heol daebak (chuka chuka)]

  Whoa, amazing, congrats!

• ㄱㅅㄱㅅ ㅋㅋㅋ 같이 갈래?

  [(gamsa gamsa) gachi gallae]

  Thanks thanks lol, want to go together?

• ㅇㅇ 당연하지 ㅠㅠ

  [(eungeung) dangyeonhaji]

  Yeah, of course (so touched)

Politeness still matters

Slang is mostly for friends and casual online spaces. With teachers, coworkers, and people you do not know well, keep messages in polite 해요체. A light ㅎㅎ or a friendly emoji is usually fine, but consonant abbreviations can seem careless in a work message.

• 네, 알겠습니다. 감사합니다!

  [ne algetseumnida gamsahamnida]

  Yes, understood. Thank you!

• 내일 뵙겠습니다 ㅎㅎ

  [naeil boepgetseumnida ㅎㅎ]

  See you tomorrow hehe (polite but friendly)

Reading tone in messages

Korean chats rely on small signals. A message ending in a period can feel serious or cold, while one ending with ㅎㅎ or an emoji feels friendly. Replying with only ㅇ can seem curt. Watch how your friends write and mirror their style.

Slang changes fast

Internet slang evolves quickly, and trendy words can sound outdated within a year. Learn the stable basics above, which have been common for many years, and pick up newer expressions from friends as they appear.

Typing ㅋㅋ and ㅠㅠ

To type these, add a Korean keyboard in your phone or computer settings. On the standard two-set Korean layout, ㅋ is on the Z key, ㅎ on G, ㅇ on D, ㅠ on B, and ㅜ on N. So a quick ㅋㅋㅋ is just Z Z Z.

Texting slang is one of the most fun parts of modern Korean. It adds personality and warmth to your messages and helps you feel part of the conversation.
