If you’ve ever watched a K-drama, followed a K-pop group, or scrolled through Korean TikTok (a.k.a. TikTok Korea), you’ve probably come across slang words that left you staring at your screen thinking, “Wait, what did they just say?”
Welcome to the colorful, ever-evolving world of Korean slang — where language meets pop culture, humor meets creativity, and every word has its own flair.
Korean slang, or yuhokmal (유행말), reflects the heart of modern Korean society — youthful, expressive, and always changing. From online communities to bustling Seoul cafes, these phrases shape how people talk, joke, and connect.
Let’s explore what Korean slang really is, the most popular terms in 2025, and how you can use them like a local (without sounding like you copied straight from Google Translate 😅).
What Is Korean Slang?
Korean slang refers to informal expressions, abbreviations, and trendy words commonly used in daily conversations, especially by younger generations and online communities.
It’s like American internet slang — words such as “lit,” “sus,” or “cringe” — but with a uniquely Korean twist. These words reflect humor, emotion, and personality.
Slang is also a huge part of Korean digital culture — found in chatrooms, K-pop fandoms, memes, and YouTube comments.
For example:
- “Jjang (짱)” = awesome or cool
- “Daebak (대박)” = amazing, jackpot, unbelievable
- “Aigoo (아이구)” = an exclamation like “oh my gosh” or “geez”
Simple, right? But each word carries cultural weight, emotion, and context that make them fascinating to learn.

How Korean Slang Reflects Culture
Korean slang isn’t just funny — it’s cultural storytelling.
Each slang word mirrors modern Korean society’s values: humor, speed, creativity, and connection.
For example:
- Respect meets playfulness: Even in casual speech, Korean slang maintains politeness — a reflection of hierarchical culture.
- Creativity through wordplay: Koreans love puns, abbreviations, and blended English terms (called Konglish).
- Digital influence: Platforms like Naver, KakaoTalk, and YouTube shape new slang daily.
So, learning Korean slang is like understanding Korea’s cultural heartbeat — dynamic, expressive, and always online.
Popular Korean Slang in K-Pop and K-Dramas
K-pop and K-dramas are global slang factories. Every time a K-pop idol says something cute, it becomes a meme within hours.
Some examples:
- “Borahae” (보라해) — coined by BTS’s V, means “I purple you,” symbolizing long-lasting love and trust.
- “Fighting!” (화이팅) — means “Let’s go!” or “You can do it!”
- “Oppa” (오빠) — used by women to refer to older men affectionately.
- “Maknae” (막내) — means the youngest member of a group.
Even global fans now use these words casually on Twitter and TikTok.
“Lisa is such a cool unnie 😍”
“That dance break was daebak!”
Language meets fandom — and that’s why Korean slang travels fast.
Internet and Texting Slang Koreans Actually Use
Modern Korean slang thrives online — especially in texting. Here are a few that’ll make you sound instantly fluent in internet Korean:
| Slang | Meaning | Example |
|---|---|---|
| ㅋㅋㅋ (kekeke) | Laughter, like “LOL” | “That meme is too funny ㅋㅋㅋ” |
| ㄱㄱ (g g) | Go go / Let’s do it | “Party tonight? ㄱㄱ” |
| ㅎㅇ (h i) | Hi | “ㅎㅇ 친구 (Hi, friend)” |
| ㄴㄴ | No no | “ㄴㄴ, not today” |
| ㄹㅇ (r e a l) | For real | “ㄹㅇ daebak!” |
| ㅇㅋ | OK | “ㅇㅋ see u there” |
| ㅂㅂ | Bye bye | “ㅂㅂ~ talk later!” |
These short forms dominate KakaoTalk, Twitter, and Instagram comments — fast, funny, and totally Gen Z.
Regional and Generational Differences in Korean Slang
Not all slang is universal.
- Older Koreans often find Gen Z slang confusing.
- Regional dialects (like Busan or Jeju) add their own flavor.
For instance:
- In Seoul, “Jjang!” means awesome.
- In Busan, they might say “Jalma!” — same idea, different vibe.
Korean slang is like music — every generation remixes it.

If you love K-pop, K-dramas, or Korean culture, learning slang gives you:
- Cultural connection: You’ll understand memes, lyrics, and jokes better.
- Social fluency: You’ll sound natural chatting with Korean friends online.

And honestly? It’s fun. Saying “daebak” just feels good.
