Slang FAQ
ㅋㅋ is Korean texting laughter — the consonant ㅋ (k) repeated, like 'kkkk'. More ㅋ means harder laughing: ㅋㅋㅋㅋㅋ is a real laugh, while a single ㅋ can read as dry or sarcastic. The softer alternative is ㅎㅎ, a gentle chuckle.
헐 (heol) is the Korean 'OMG' — a gasp of disbelief, used for both good and bad surprises. It's often sent alone as a complete reply: 헐…
대박 (daebak) literally means 'jackpot' but works as an all-purpose exclamation: amazing, incredible, no way. Koreans use it for good news, bad news, and everything shocking in between.
갑분싸 (gap-bun-ssa) is an abbreviation of 갑자기 분위기 싸해짐 — 'the mood suddenly turned cold'. It describes the moment someone kills the vibe, like a joke landing badly.
No — most slang and 초성체 abbreviations are for close friends and same-age or younger people. Using ㅇㅇ or ㄱㅅ with your boss or an older person would come across as rude; stick to polite forms like 네 and 감사합니다 there.
