Korean Slang: 60+ Words, Phrases and Texting Shortcuts
Full disclosure: This post contains affiliate links. ?
Korean slang can help you follow group chats, variety shows, webtoons and conversations between close friends. It can also make a learner sound rude, dated or oddly theatrical when the relationship and setting are wrong.
Treat this as a recognition guide first. Slang changes quickly, and English glosses such as “awesome” or “OMG” only describe one possible effect. The safer question is: who said this to whom, in what situation, and what happened next?
The National Institute of Korean Language’s Korean–English Learners’ Dictionary is useful for established words, while its participatory Urimalsaem search includes newer and informal forms. A dictionary entry does not prove that a term is current in every age group or community, so check recent examples too.

Basic Korean Slang Words to Get You Started
Start with expressions you are likely to recognise. Keep the Hangul in your notes: romanisation is only a prompt, and it cannot capture every Korean sound or sound change. The National Institute’s language-rules portal gives the official Revised Romanization system.
대박 (daebak): a Big Success or “Wow”
The core noun 대박 refers to a great success or a big hit. In casual speech, 대박! can react to impressive or surprising news: “Wow!”, “That’s amazing” or, with a different tone, “Seriously?” The official learner’s-dictionary entry shows the success meaning in phrases such as 대박이 나다, “to become a big hit”.
Example: 시험 붙었어? 대박! (Siheom buteosseo? Daebak!) means “You passed the exam? Wow!” Use it with someone you already speak casually with.
헐 (heol): Surprise or Disbelief
헐 is a short reaction to surprise, disbelief, awkwardness or dismay. “OMG” can fit; “WTF” is often much stronger than the Korean expression. Tone and the following sentence do most of the work.
Example: 헐, 벌써 끝났어? (Heol, beolsseo kkeunnasseo?) means “Whoa, is it over already?”
짱 (jjang): “The Best” or “Cool”
짱 can mean “the best” or describe someone or something as excellent. It also appears in compounds such as 몸짱, a person known for a highly developed physique. It is casual and can feel more playful or retro than a neutral compliment.
Example: 이 노래 짱이다. (I norae jjang-ida.) means “This song is brilliant.”
애교 (aegyo): Performed Cuteness
애교 is not simply the adjective “cute”, and it is not a way of dressing. It is affectionate or deliberately cute behaviour expressed through voice, wording, facial expression or gestures. It may be playful between close people or performed for an audience; copying it without knowing the social frame can feel uncomfortable.
For ordinary ways to describe something as cute, see our guide to “cute” in Korean.
꿀잼 and Other Positive Reactions
꿀잼 (kkuljaem) means that something is very entertaining. 꿀, “honey”, intensifies 잼, a clipped form associated with 재미, “fun”. It is especially natural when reacting to content or an experience: 이 드라마 꿀잼이야, “This drama is so entertaining.”
| Expression | Working meaning | Register note |
|---|---|---|
| 실화야? (silhwaya?) | “Is this for real?” | Casual reaction; 실화 also literally means a true story. |
| 쩐다 / 쩔어 (jjeonda / jjeoreo) | “That’s intense / amazing” | Rough casual speech; admiration or shock depends on tone. |
| 오졌다 (ojyeotda) | “That was wild / incredible” | Rough and potentially vulgar; recognise before using. |
| 포스 있다 (poseu itda) | “They have presence / an aura” | 포스 is an English-derived loan, but the phrase is not specifically a Star Wars reference. |
| 세상에 (sesange) | “Goodness / what in the world” | An established exclamation, not necessarily youth slang. |
노잼 and Reactions That Need More Care
노잼 (nojaem) means “not fun” or “boring”. It is not a literal Korean version of “not the jam”. 썰렁하다 can describe a chilly atmosphere or an awkward, flat joke; it does not mean “sloppy”.
화이팅 or 파이팅: Encouragement
화이팅! (hwaiting) and 파이팅! (paiting) encourage someone: “You’ve got this!”, “Go for it!” or “Good luck!” They derive from English fighting, but English speakers do not normally use the source word this way.
Example: 오늘 면접 화이팅! (Oneul myeonjeop hwaiting!) means “Good luck with your interview today!”
극혐 (geukhyeom): Strong Disgust
극혐 abbreviates 극한의 혐오, “extreme disgust”. It is a harsh label, not a light substitute for “I don’t like it”. Avoid directing it at a person or group; even among friends, it can sound contemptuous.
심쿵 (simkung): a Heart-Thump Moment
심쿵 combines 심장, “heart”, with 쿵, a thumping sound. It describes the jolt or flutter of your heart after something exciting, romantic or startling. It can describe a fan reaction, but it does not mean “fangirling” by itself.
솔까말 (solkkamal): “To Be Frank”
솔까말 is a clipped form of 솔직히 까놓고 말해서, roughly “to speak openly and honestly”. It works like “to be frank” or “TBH”, though many speakers may simply say 솔직히. Treat it as an expression you may encounter rather than a compulsory upgrade to your Korean.
Korean Slang Phrases in Context
These expressions come from several registers. A label such as casual means you still need the right relationship; it does not mean “safe with everyone”.
| Expression | Meaning | What to notice |
|---|---|---|
| 안물안궁 (anmul-angung) | “Didn’t ask, don’t care” | Dismissive abbreviation; useful to recognise, risky to direct at someone. |
| 셀카 (selka) | Selfie | A settled blend of 셀프 and 카메라; now ordinary informal vocabulary. |
| 눈팅 (nunting) | Reading or watching online without posting | Similar to “lurking”, without necessarily implying stalking. |
| 불금 (bulgeum) | A lively Friday night | Short for 불타는 금요일, “burning Friday”. |
| 맛점 (matjeom) | A tasty/enjoyable lunch | Chatty clipping of 맛있는 점심; can work as a lunchtime greeting. |
| 최애 (choeae) | Favourite person or member | Literally “most loved”; frequent in fandom contexts. |
| 덕질 (deokjil) | Doing fan activities | Covers the time, attention and collecting involved in a fandom. |
| 뻥치지 마 (ppeongchiji ma) | “Don’t lie / don’t kid me” | Informal command; spacing matters, and tone can be playful or accusatory. |
Modern Korean Slang and Abbreviations
A 2024 study of Korean acronyms and clipped forms notes that some internet forms disappear quickly while others spread because they are concise and their meanings remain recoverable. That is why a dated list should not present every coinage as permanent everyday Korean.
Not Every Casual Word Is Slang
마스크 (maseukeu, “mask”), 어떻게 (eotteoke, “how/what should I do?”), 사랑해요 (saranghaeyo, “I love you”) and 보고 싶어 (bogo sipeo, “I miss you”) are ordinary Korean expressions, not slang. A phrase can be common in dramas or casual speech without belonging in a slang list.
혼- Compounds for Doing Things Alone
혼- compounds build on 혼자, “alone”. They describe solo activities; they do not automatically imply loneliness.
| Term | Meaning | Formation |
|---|---|---|
| 혼족 (honjok) | People who pursue activities alone | 혼 + 족, “group/tribe”. |
| 혼밥 (honbap) | Eating alone | 혼자 + 밥. |
| 혼술 (honsul) | Drinking alcohol alone | 혼자 + 술. |
| 혼영 (honyeong) | Watching a film alone | 혼자 + 영화. |
| 혼행 (honhaeng) | Solo travel | 혼자 + 여행. |
| 혼코노 (honkono) | Going alone to coin karaoke | 혼자 + 코인 노래방. |
| 혼놀 (honnol) | Playing or spending leisure time alone | 혼자 + 놀다; not a synonym limited to karaoke. |
Shortened Compounds Can Age Quickly
인싸 (inssa) and 아싸 (assa) came from “insider” and “outsider”. In casual Korean, 인싸 often suggests a socially connected person, while 아싸 can describe someone outside the main social circle. 핵인싸 (haeg-inssa) intensifies 인싸. These labels can be playful, but they can also flatten a person into a social stereotype.
Do not assume a new-looking compound is widely current because it appeared in one trend article. Search a recent corpus or social feed, check who is using it and ask a trusted speaker whether it sounds current, ironic or dated.
멘붕 (menbung): Feeling Mentally Thrown
멘붕 clips 멘탈 붕괴, literally “mental collapse”. In everyday informal use it can mean feeling overwhelmed, confused or mentally thrown. It is not a clinical diagnosis, and it did not originate with the COVID-19 pandemic.
이생망 (isaengmang) clips 이번 생은 망했다, “this life is ruined”. It is dramatic internet shorthand for feeling that something has gone badly. Because jokes about despair can land differently for different people, copy the context rather than assuming it is harmless.
Money-and-Mood Compounds
홧김비용 (hwatgim biyong) is spending caused by anger or acting “in the heat of the moment”; it is narrower than impulse shopping in general. 나심비 (nasimbi) describes spending judged by personal satisfaction, while 멍청비용 (meongcheong biyong) is money lost through one’s own mistake. These labels are useful for understanding headlines and conversation, but their popularity can rise and fall.
Cute Korean Texting Signals
Cute tone in Korean is not made by adding m or ng to any word. Speakers use spelling, repeated marks, emoji, sentence endings, voice and shared expectations. Copying one surface feature without the relationship can sound forced.
| Signal | Typical effect | Caution |
|---|---|---|
| ㅋㅋ / ㅋㅋㅋ | Laughter, often like “haha” | A single ㅋ can feel dry; the number and context change the tone. |
| ㅎㅎ / ㅎㅎㅎ | Softer laughter or a warm chuckle | Can also soften an awkward message. |
| ㅠㅠ / ㅜㅜ | Crying face made from vowels | Can show real sadness, sympathy or playful disappointment. |
| ~~ | Lengthened, light or affectionate tone | Not automatically cute in every message. |
| 행쇼 (haengsyo) | A clipped “be happy” sign-off | Associated with an older catchphrase and may sound dated or referential. |
A 2025 study of 응 and 어 variants in KakaoTalk conversations found that messenger forms vary with speaker and conversational function. That is a good reminder that one spelling does not carry one fixed emotion.
Gaming, Fandom and Strong Informal Words
| Term | Meaning | Register |
|---|---|---|
| 만렙 (manrep) | Maximum level; figuratively, highly skilled | Gaming term used metaphorically. |
| 쪼렙 (jjorep) | Low-level player or novice | Casual; can be self-deprecating or belittling. |
| 치맥 (chimaek) | Fried chicken and beer | Blend of 치킨 and 맥주. |
| 사차원 (sachawon) | “Fourth-dimensional”; eccentric or unpredictable | Can sound dated and can be unkind when labelling a person. |
| 간지 (ganji) | Style, flair or swagger | Informal; derived from Japanese 感じ. |
| 존맛 / 존맛탱 (jonmat / jonmattaeng) | Extremely delicious | The first element comes from a vulgar intensifier; do not present it as neutral. |
| JMT | Latin-letter abbreviation of 존맛탱 | Informal online form with the same vulgar origin. |
| 킹받네 (kingbanne) | “This is so irritating” | Playful internet intensification of 열받네; trend-sensitive. |
Korean Text and Internet Slang
Initial-consonant forms are easiest to recognise after you know the full Korean expression. Do not pronounce every item as a string of English letter names.

How to Learn Korean Slang Without Forcing It
The goal is not to insert slang into every sentence. It is to understand what another person is doing with it, then decide whether the same move fits your relationship.
- Capture the whole line. Save the sentence before and after the slang, plus the speaker, audience and setting.
- Mark the relationship. Note age, closeness, workplace or school hierarchy, and whether the speakers already use 반말 (banmal) with each other.
- Check the base expression. Use the official learner’s dictionary for established vocabulary and Urimalsaem or a recent corpus for newer forms.
- Copy the function, not the English gloss. Was the speaker praising, teasing, refusing, softening or showing disbelief?
- Test one expression with a trusted speaker. Ask whether it sounds current and whether they would say it to you in that setting.
The National Institute’s guide to polite Korean explains that adults of similar ages commonly begin with polite forms and move to informal speech after becoming closer and agreeing on the shift. “Same age” is not an automatic licence to use slang.
