Korean Texting Slang: What Koreans Actually Type

If you've ever looked at a Korean group chat and felt completely lost despite knowing "proper" Korean, you're not alone. Korean texting slang (줄임말) is a whole different language. These abbreviations and expressions are everywhere — KakaoTalk, Instagram comments, YouTube, Naver cafés.

Here are 35 expressions you'll actually encounter.

Consonant-Only Abbreviations

Koreans often type just the initial consonants (초성, choseong) of a word. This is the most common form of texting shorthand:

How to read 초성

On a Korean keyboard, each consonant maps to the first sound of a syllable. So ㅋㅋㅋ is the "k" sound from 크 (keu) — repeated, it mimics laughing. The more ㅋ's, the funnier something is. One ㅋ can actually feel dismissive.

Number-Based Slang

Common Abbreviations

Reaction Expressions

These show up constantly in chats and comments:

Emoticon Style (이모티콘)

Korean emoticons don't use Western-style :) faces. Instead:

Note: Adding ㅋ at the end softens messages. "뭐해" (what are you doing) can feel blunt. "뭐해ㅋㅋ" feels casual and friendly.

How to Practice

1. Watch Korean YouTube comments — They're a goldmine of real slang
2. Join a KakaoTalk group — Even language exchange groups use slang constantly
3. Follow Korean meme accounts on Instagram
4. Don't memorize — absorb — You'll pick these up naturally with exposure

A Warning About Formality

Texting slang is for casual contexts only. Never use these in:

• Work emails
• Messages to someone older (unless they use it first)
• Formal writing of any kind

Using ㅋㅋ with your boss is a career decision. Choose wisely.
