Korean Slang & Cute Expressions (애교) for Texting

The casual Korean you won't find in a textbook: real texting slang and abbreviations (ㅋㅋ, ㅠㅠ, ㄱㄱ), plus cute 애교 expressions — with meaning, usage, and when to use them.

Updated

Textbooks teach you proper Korean, but real chats are full of slang, abbreviations, and cute expressions that no lesson covers. If you've ever seen a Korean text full of ㅋㅋㅋ and ㅠㅠ and felt lost, this guide is for you. Below are the most common pieces of casual, online Korean — what they mean, how they're used, and when to keep them out of polite conversation. (Everything here is PG-13 and safe for everyday use.)

Texting abbreviations (초성체)

Koreans love typing just the consonants of a word — a shorthand called 초성체 (choseongche, 'initial-consonant writing'). It's fast and very common in chats. Here are the essentials:

  • ㅋㅋㅋkkk

    lol / haha

    From ㅋ (k). More ㅋ = harder laughing. The most common one of all.

  • ㅎㅎhh

    hehe (soft laugh)

    From ㅎ (h). Gentler and warmer than ㅋㅋ.

  • ㅠㅠyu yu

    crying / aww

    The vowels look like teary eyes. ㅜㅜ is the same idea.

  • ㄱㄱg g

    let's go / go go

    From 고고 (gogo). Short for 'go ahead'.

  • ㅇㅇeung eung

    yeah / yep (casual yes)

    From 응 (eung), a casual 'yes'. ㄴㄴ (no no) is the casual 'no'.

  • ㄱㅅg s

    thanks

    Initials of 감사 (gamsa, 'thanks').

Everyday slang words

  • 대박daebak

    awesome / no way!

    All-purpose exclamation for something amazing or shocking — good or bad.

  • 헐heol

    whoa / OMG

    A reaction of surprise or disbelief. Very common in chats.

  • 짱jjang

    the best / awesome

    Add it to anything: 맛짱 = super tasty.

  • 꿀잼kkuljaem

    super fun

    꿀 (honey) + 잼 (short for 재미, 'fun'). The opposite is 노잼 (nojaem, 'no fun').

  • 케바케kebake

    it depends (case by case)

    Korean-ized abbreviation of 'case by case'.

애교: cute expressions

애교 (aegyo) is the art of being cute and charming — softer phrasing, drawn-out vowels, and sweet little add-ons. It's playful and affectionate, used a lot between couples and close friends. A light touch goes a long way.

  • 보고 싶어용bogo sipeoyong

    I miss you~ (cutesy)

    Adding -용 instead of -요 softens it into something playful and cute.

  • 알았어용arasseoyong

    okaaay~

    The cute -용 ending again. Stretching vowels in text (알았오옹) adds more 애교.

  • 뭐해?mwohae?

    whatcha doing?

    A super common casual text opener. 뭐 해 = 'what (are you) doing'.

  • 잘 자jal ja

    sleep well / good night

    Sweet sign-off to someone close. Polite version: 잘 자요.

A word on register

All of this is casual 반말, the speech you use with friends and people younger than you. Keep slang and 애교 out of conversations with elders, teachers, bosses, or strangers — there it reads as disrespectful. The skill isn't just knowing the words; it's reading the situation and switching registers smoothly. That instinct comes from practice.

The safest place to try out slang and cute expressions is a low-stakes chat where nobody gets offended. In our AI character chat, you can text casually, throw in a ㅋㅋ or some 애교, and see how a character responds in natural Korean — building a feel for what sounds friendly versus over the top. For the formal side of the same coin, see how 사랑해 changes across levels in our guide to saying 'I love you' in Korean.

Frequently asked questions

What does ㅋㅋ mean in Korean?

ㅋㅋ (often written ㅋㅋㅋ) is the Korean equivalent of 'lol' or 'haha'. ㅋ is the consonant that makes a 'k' sound, so repeating it represents laughter — 'kkkk'. More ㅋ means harder laughing. ㅎㅎ (from ㅎ, an 'h' sound) is a softer, gentler giggle.

Is it okay for a beginner to use Korean slang?

Yes, in casual settings with friends or in text. Slang and abbreviations are 반말 (casual speech), so avoid them with elders, teachers, or in formal situations — there it can read as disrespectful. Used with peers, slang makes you sound natural and friendly.

What is 애교 (aegyo)?

애교 (aegyo) is acting cute or charming — a softer voice, playful phrasing, drawn-out endings, and sweet little expressions, often to be endearing or to win someone over. It's common between couples and close friends and is a big part of casual Korean culture, especially online and in K-pop.

What does ㅠㅠ mean?

ㅠㅠ (or ㅜㅜ) represents crying — the vowels look like teary eyes. It can mean genuine sadness, mock-sadness, or 'aww, poor you', depending on context. It's one of the most common emoticons in Korean texting.
