Korean Internet Slang for Webtoon and K-Drama Fans (2026)

Korean internet slang is the first wall you hit when you scroll past the last panel of a webtoon or open the comments under a drama clip. Textbooks skip it, and most slang lists online mix 2010s words that nobody uses anymore with crude ones you'd never want to say to a coworker. This guide sorts the slang you'll actually meet as a fan, and notes for each word how rude or dated it is.

It's for learners from about TOPIK 2 who can read Hangul comfortably and want to follow comments, reviews and variety show captions. Every entry has Hangul, Revised Romanization, meaning, where you'll see it and its register.

How Korean internet slang is built

Most new words come from four tricks, and once you know them you can often decode slang you've never seen:

• Initial consonants only (초성, choseong): ㄱㅅ for 감사 (thanks). Fast to type, and common in chats and comments.
• First syllables of a phrase (줄임말, jurimmal): 갑자기 분위기 싸해짐 becomes 갑분싸. Koreans even have a slang word for this habit: 별다줄, "you shorten everything."
• Visual puns (야민정음, yaminjeongeum): letters swapped for ones that look alike, so 명작 (masterpiece) becomes 띵작.
• Memes from people: a celebrity's catchphrase, a gamer's interview or a dialect joke spreads and becomes a word for a year or two.

Chat shorthand: ㅋㅋ, ㅇㅇ and other consonant codes

These are typed, not said, though young people sometimes read a few aloud as a joke. Romanizations show the letters or the sound they stand for.

Shortened phrases and everyday slang

These come up in dialogue in modern dramas and constantly in variety show captions. Some have been around for 15 years and are now just ordinary casual Korean.

Two prefixes are worth extra care. 개- and 존- both intensify, but 존- comes from a vulgar word, so 존맛 and 존잼 are for close friends only. When in doubt, use 진짜 or 너무 instead.

K-drama fan slang: goguma, saida and second leads

These are the words Korean viewers use to talk about plots, and you'll see them in every review thread and comment section. 고구마 and 사이다 are the big pair: a sweet potato gets stuck in your throat, and a fizzy soda clears it.

Webtoon slang: the comment section and the platform

Webtoon readers have their own vocabulary, part platform jargon and part comment culture. If you read on Naver Webtoon or Kakao, you'll see these on every episode page.

Is Korean internet slang rude?

Most of it isn't rude, just casual. Consonant codes, 고구마 and 정주행 are fine with friends and in comments. The problems are a small group of words with vulgar roots, like 존맛, and anything typed to someone older: answering a manager with ㅇㅇ reads as dismissive. Slang also dates fast. 멘붕 and 심쿵 still work but feel 2010s, and kids' slang like 어쩔티비 peaks and fades within a couple of years.

Common learner mistakes with Korean slang

• Saying chat codes out loud. ㅇㅈ is typed; in speech, say 인정.
• Using slang with polite endings in the wrong place. 킹받네요 to a teacher sounds odd. Slang and formal settings don't mix.
• Learning slang before basics. Slang is built on the standard word. You'll decode 갑분싸 only if you know 갑자기 and 분위기.
• Trusting old lists. Many top-ranking lists still teach early-2010s words as current. Check how recent a word is before you use it.

How to learn slang from webtoons and variety shows

1. Read the best comments. After each webtoon episode, read the top five 베댓. They're short, funny and full of current slang. Our guide to how to learn Korean from webtoons covers the reading side.
2. Watch variety captions. Korean variety shows put slang-heavy captions on screen. Pause and read them. The picks in the best Korean variety shows for learners are a good start.
3. Keep a slang list separate from your main deck. Tag each word with its register and the year you met it, so you don't drill words that are already out of date.
4. Pair it with drama vocabulary. The K-drama phrases glossary covers the spoken lines that slang often plays on.

Track your Korean input

Comment sections and captions count as reading practice, even when they feel like scrolling. Log webtoon chapters and episodes in LangTrack to see how much real Korean you take in each week, and which kind of input you're light on.

Frequently asked questions

What does ㅋㅋ mean in Korean?

ㅋㅋ is laughter, like "lol" or "haha." It comes from the sound of the letter ㅋ, and more letters mean more laughing. ㅎㅎ is a softer, friendlier smile.

What do goguma and saida mean in K-drama reviews?

Goguma (고구마, sweet potato) describes a frustrating, stuck plot, like a dry sweet potato caught in your throat. Saida (사이다, soda) is the opposite: a satisfying, refreshing payoff.

What does hyujae mean on webtoons?

Hyujae (휴재) means a hiatus, a week or longer when the creator doesn't publish a new episode. Wangyeol (완결) means the series is complete.

Is it okay for learners to use Korean slang?

Yes, with friends your age and in comments, as long as you avoid words with vulgar roots like 존맛. With teachers, coworkers and anyone older, stick to standard polite Korean.
