Squid Game pulled half a billion people into Korean dialogue almost overnight. But Netflix subtitles compress, paraphrase, and sometimes flatten what's happening — leaving viewers with the plot but missing the language. Here are the 5 Korean phrases from the show you'll actually hear in everyday life, and one bonus chant every Korean knows by heart.
1. 깐부 (ggan-bu) — your ride-or-die
The most iconic word the show gave the world. Old Man Oh Il-nam says it to Player 456 right before the marbles game: "You and I are 깐부." Netflix translated it as "partner," but that misses the weight.
깐부 is the friend you trust completely — the one you'd split your last marble with, the one whose back you'd never turn on. It comes from old Korean children's slang for "ride-or-die teammate." Adults rarely use it in formal speech, but when they do, it lands hard. It's a declaration of loyalty disguised as a casual word.
How to use it: "우리 깐부지?" (uri ggan-bu-ji?) — "We're ride-or-die, right?" Said to a close friend before you ask them an outrageous favor.
2. 빨리빨리 (ppal-li ppal-li) — Korea's national tempo
You hear it once a minute in Korea. 빨리빨리 literally means "fast fast" — and it captures something deep about Korean life: get things done, now, with no wasted motion. In Squid Game it's barked at players by guards; in real life it's barked at slow elevators, slow waiters, and slow children.
Korea's "ppalli-ppalli culture" (빨리빨리 문화) is so well-known that it has its own English Wikipedia page. It's the reason Korean food comes out in five minutes, Korean delivery shows up in twenty, and Korean broadband is the fastest in the world. It's not rude — it's the rhythm.
How to use it: Say it to a friend you're waiting on. Say it cheerfully. They will not be offended.
3. 미안해 (mi-an-hae) — sorry, casual
The casual "sorry" between people who know each other well. Squid Game's emotional gut-punches almost all carry a 미안해 — usually from a player who couldn't save someone, or from a parent who couldn't protect a child.
The polite version is 미안해요 (mianhaeyo) and the formal is 죄송합니다 (joesonghamnida) — used with strangers, elders, bosses. Save 미안해 for the friends and family you're close with. To everyone else, default up the politeness ladder.
How to use it: To a friend who you accidentally bumped into — "아 미안해!" (ah mianhae!) — "Oh, sorry!" Light. Warm. Human.
4. 도와주세요 (do-wa-ju-se-yo) — please help me
The phrase that saves your life — literally, in the show, and probably figuratively, on your first trip to Seoul. 도와주세요 is the polite "please help me," and it's one of the most useful phrases in Korean for travelers and beginners.
Breakdown: 도와 (dowa, "help") + 주세요 (juseyo, "please give me"). You're literally asking someone to "give you help." It works for everything: lost in the subway, can't read a menu, dropped your phone, locked out of your Airbnb.
How to use it: Walk up to a Korean stranger, make eye contact, say "저기요, 도와주세요" (jeogiyo, dowajuseyo) — "Excuse me, please help me." Koreans will almost always stop and help. It's a cultural reflex.
5. 괜찮아요 (gwaen-chan-a-yo) — it's okay / are you okay
The Swiss Army knife of Korean. 괜찮아요 means "it's okay" — but also "I'm fine," "are you okay?," "no thanks," "don't worry about it," and a dozen other things depending on tone and context.
In Squid Game it shows up at every emotional climax. A character drops to the ground; another rushes over: "괜찮아요?" — "Are you okay?" A character offers a stranger food; she waves it off: "괜찮아요" — "I'm fine, thanks." A character apologizes; the other forgives: "괜찮아요" — "It's okay."
How to use it: If you only learn one Korean phrase, this is the one. Rising tone (괜찮아요?) asks the question. Flat or falling tone (괜찮아요) answers it.
Bonus: 무궁화 꽃이 피었습니다 — the red-light, green-light chant
The most chilling line of the show. The giant doll turns her head and sings: "무궁화 꽃이 피었습니다" (mu-gung-hwa kko-chi pi-eot-seum-ni-da) — "The mugunghwa flower has bloomed." Move while she's singing; freeze when she stops.
It's the Korean version of "red light, green light," and every Korean child has played it. The phrase is a beautiful one in Korean — 무궁화 is the national flower (Rose of Sharon). The full sentence is in formal speech (-습니다 ending), which is part of why it sounds eerie and almost ceremonial. A schoolyard chant, spoken like a state announcement.
You'll never use this phrase in conversation — but every Korean recognizes it instantly, and dropping it (e.g. on a friend's Instagram story of them in a frozen yoga pose) earns you an immediate cultural insider point.
What Squid Game actually teaches about Korean
Watching the show with subtitles teaches you plot. Watching it with these phrases in your head teaches you Korean. Three patterns to notice on rewatch:
- Politeness levels shift constantly. The same character uses 미안해 with one friend and 죄송합니다 with another. Korean is built on these registers — and the show is a free masterclass.
- 괜찮아요 carries the emotional weight. Count how many times it appears in episodes 5–9. It's used to comfort, to deflect, to forgive, to lie. The single phrase compresses entire scenes of subtext.
- Old slang becomes Gen-Z slang. 깐부 was almost dead before the show — Squid Game gave it a second life. K-content does this constantly: every K-drama hit retires some phrases and revives others.
