사기캐 (sagikae) — The Compliment for Someone So Good It Feels Like Cheating
사기캐
사기캐 (sagikae) is a word for someone whose ability or circumstances are so outstanding that it feels like cheating. It started as gamer talk for “a character so strong on its own that it breaks the balance of the match,” then walked out of the game world — and now it gets attached to people and to objects alike.
Picture a scene. A new hire joins the company: fast at the work, can hold their liquor, and it turns out they’ve even finished a marathon. Two senior colleagues, getting coffee in the break room, mutter: 쟤 뭐야. 사기캐야? (jyae mwoya. sagikaeya?) — “What’s with that guy? Is he a sagikae?” That line is eighty percent praise and twenty percent grievance. You admit the person is impressive, but being told to compete with them on equal footing feels a little unfair. The temperature of 사기캐 sits exactly there.
So the word is a bit different from a pure compliment. 대단하다 (daedanhada), “that’s amazing,” lifts the other person up; 사기캐 (sagikae) is closer to a joking protest — “that one person is having the rules applied differently.” It sounds like a complaint but lands as admiration, and that’s the fun of the expression. The person hearing it usually doesn’t mind, either. More often they laugh and say 에이, 무슨 (ei, museun) — “Oh, come on.”
Its range is wide, too. It’s used for people most of all, but it also gets attached to objects that perform absurdly well: earbuds whose battery lasts three days, a kimchi fridge where two-month-old kimchi is still perfect, a 백반집 (baekbanjip) — a home-style set-meal diner — where ten thousand won gets you five side dishes. Saying 이거 사기캐다 (igeo sagikaeda) about these things means “considering the price or the size, this is unreasonably good.”
That said, it is strictly slang used among peers. Because the word contains 사기 (sagi, 詐欺), meaning “fraud,” the most common misunderstanding among Korean learners is “Isn’t this like 사기꾼 (sagikkun), a con artist?” — it’s the exact opposite. A 사기캐 isn’t someone who deceives you; it’s someone so good that you feel deceived.
See It in a Real Conversation
Scene: Saturday morning at the neighborhood gym, a badminton club. Sitting on the bench next to the court right after a doubles match, drinking water.
Jun-kyung: 야, 저 사람 뭐야. 우리 둘이 붙었는데 한 게임도 못 땄어. Hey, what’s with that guy? The two of us played against him and didn’t win a single game.
Emily: 아까 라켓 처음 잡아 본다고 하지 않았어? Didn’t he say earlier that it was his first time holding a racket?
Jun-kyung: 했지. 근데 키는 백구십에, 발 빠르지, 손목 스냅까지 좋아. 완전 사기캐야. He did. But he’s 190 centimeters, quick on his feet, and even his wrist snap is good. He’s a total sagikae.
Emily: 아, 그래서 아까 팀 짤 때 다들 자기편 하라고 난리였구나. Ah, so that’s why everyone was fighting to get him on their team.
Jun-kyung: 그러니까. 저런 사기캐는 좀 너프해야 되는 거 아니야? Right? Somebody needs to nerf a sagikae like that, don’t you think?
Emily: 너프는 무슨. 그냥 우리가 연습을 더 해야지. Nerf, my foot. We just need to practice more.
This Would Sound Awkward
✗ (straight to your department head) 부장님, 영어에 골프까지 하시고… 부장님은 진짜 사기캐세요. “Sir, English and golf on top of it… you’re a real sagikae.”
✓ (to a coworker) 부장님 영어도 하시고 골프도 치시더라. 완전 사기캐야. “Turns out the boss speaks English and plays golf too. He’s a total sagikae.”
→ Since it’s slang born in games, using it to someone’s face when they’re your senior comes across as a light joke rather than praise. To the person directly, something like 정말 못 하시는 게 없으세요 (jeongmal mot hasineun ge eopseuseyo), “there’s really nothing you can’t do,” is safer. Marveling about them behind their back is no problem at all.
✗ (to a friend who just failed an exam) 어차피 걔는 사기캐라 네가 이길 수가 없었어. “He’s a sagikae anyway, so there was no way you could beat him.”
✓ (commiserating together) 걔가 좀 특이한 경우였어. 너 진짜 열심히 했잖아. “He was kind of an unusual case. You worked really hard.”
→ 사기캐 carries the sense of “that person is simply in a different class,” so used in front of the person who lost, it isn’t comfort — it’s a verdict of resignation. It’s a word for marveling at a third party, not one to place in a moment meant for consoling someone.
Example Sentences by Situation
1. When you’re surprised by a new arrival’s background
저 친구 이력 봤어? 완전 사기캐던데. (jeo chingu iryeok bwasseo? wanjeon sagikaedeondae.) Did you see that guy’s résumé? He’s a total sagikae.
Use it when someone new joins the company or the club and their career, education, and special skills are all impressive. Adding -던데 (-deonde) leaves the lingering sense of “I just saw it and was surprised,” which keeps the conversation going better than a flat 사기캐야.
2. When you discover a friend’s unexpected talent
계란찜 하나로 사기캐 인증했네. (gyeranjjim hanaro sagikae injeunghanne.) You proved you’re a sagikae with just one steamed egg dish.
For when you’re invited to a housewarming and the 계란찜 (gyeranjjim, steamed egg) your friend whipped up from leftover ingredients tastes better than a restaurant’s. 인증하다 (injeunghada) originally means “to certify, to prove,” but in current internet speech it’s often tacked on to mean “showed it beyond doubt through action.”
3. When something performs far beyond its price
이 김치냉장고 진짜 사기캐야. 두 달 전 김치가 아직 살아 있어. (i gimchinaengjanggo jinjja sagikaeya. du dal jeon gimchiga ajik sara isseo.) This kimchi fridge is a real sagikae. The kimchi from two months ago is still alive.
This is an example showing it can be used for non-human subjects too. Here 살아 있다 (sara itda), “it’s alive,” means the kimchi hasn’t turned sour and still holds its original taste — a common way Koreans describe the state of their kimchi.
Politeness Levels and Similar Expressions
사기캐 is a noun, not a verb, so changing only the predicate that follows makes it formally polite. It rises in the order 사기캐야 (sagikaeya) → 사기캐예요 (sagikaeyeyo) → 사기캐이십니다 (sagikaeisimnida). But that last form is almost never used in practice, because laying a trendy word on top of a formal ending feels like clothes that don’t match. 사기캐예요 is the natural upper limit, and even that is for a senior you’re comfortable with or a colleague close to your own age.
| Expression | Temperature / intensity | Where it’s used |
|---|---|---|
| 사기캐 (sagikae) | 8 parts awe + 2 parts grievance, with a joking edge | Peers and social media. Between people familiar with gaming culture |
| 넘사벽 (neomsabyeok) | Distance, mixed with giving up | Peers and social media. Points at the ‘gap’ itself rather than the person |
| 엄친아 (eomchina) | Envy + a touch of “enough already” | Peers. For someone born with good circumstances |
| 능력자 (neungnyeokja) | Neutral to positive, plain | Anywhere. Fine even toward someone above you |
The four expressions overlap but differ. 넘사벽 (neomsabyeok) is short for 넘을 수 없는 사차원의 벽, “a fourth-dimensional wall you can’t climb over,” and speaks to the distance between you and the target rather than the target itself. 엄친아 (eomchina) is short for 엄마 친구 아들, “mom’s friend’s son,” so its weight falls on inborn advantages. 능력자 (neungnyeokja), “capable person,” has only a faint slang flavor, so you can use it in a work messenger without hesitation. Only 사기캐 carries the joking edge of “isn’t that person cheating?”
Cultural Background — Someone Who Needs a Balance Patch
The word formation is simple: 사기 (sagi, 詐欺 · deception) + 캐 (kae, short for 캐릭터, “character”). Online gamers used to say “that character is so overpowered it’s 사기,” which hardened into 사기 캐릭터, and then — following Korean’s fondness for two-syllable words — shrank again into 사기캐. There are plenty of other words with 캐 in them: 쉬운캐 (swiunkae), an easy character for beginners, 약캐 (yakkae), a weak one, and on the opposite end 1티어 (il-tieo), top tier.
Another feature is that words from the same root tend to come along in conversation. When a game company lowers the performance of an overly strong character, that’s 너프 (neopeu, nerf); raising up the weak side is 버프 (beopeu, buff) — and both get applied to people as they are. When Jun-kyung said in the dialogue above that a sagikae like that needs a nerf, that’s exactly this usage. In this joke of talking about people as if they were game characters, you can glimpse a small wish that the world were a fair competitive match.
The channel that spread the word was broadcast media. From the 2010s on, the word appeared often in audition-show and sports-broadcast subtitles introducing an overwhelming contestant or athlete, and the meaning carried over even to generations that don’t play games. People in their thirties and forties understand it easily now, but for someone over sixty it may need explaining. When using it with someone unfamiliar, wrapping it in a layer — 요즘 말로 사기캐라고 하죠 (yojeum mallo sagikaerago hajyo), “in today’s slang, they call it sagikae” — makes it go down much more smoothly.
It’s also worth thinking about why this word sticks so well in Korean society. In a culture with a strong sense of “competing under the same conditions” — exams, hiring, even picking teams at a hobby club — it precisely captures the feeling of meeting someone whose conditions are simply different. The other person has done nothing wrong, so you can’t be angry; but admitting defeat outright feels a little unfair. One word speaks for you from that ambiguous spot.

Answer: 3
Number 1 is the classic misunderstanding caused by the letters 사기. Someone who actually swindles others must be called 사기꾼 (sagikkun). Number 2 is grammatically fine, but stacking the highest honorific ending onto a slang word in front of the chairman is awkward. Number 4 fails because the expression describes the outstanding performance of a person or thing, so it can’t be used for an emotional state. As in number 3, the most typical use is peers marveling together when one person is exceptionally good in several areas at once.
