Korean livestream slang

Live Korean is fast, informal and half-abbreviated. These are the words idols actually say — and the ones generic translators either skip or translate into something oddly formal.

Korean	Romanised	What it means	Why translators miss it
실화냐	silhwanya	"Is this for real?" — disbelief, usually delighted.	Becomes "is it a true story", which is technically literal and completely wrong in tone.
인정	injeong	"Agreed" / "true" — a quick note of agreement, often on its own.	Rendered as "recognition" or "acknowledgement", which reads like a legal document.
존맛	jonmat	"Incredibly tasty" — intensified slang, common on eating streams.	Often dropped entirely because the intensifier is non-standard Korean.
ㄱㅅ	gs (감사)	Consonant shorthand for "thanks", typed in chat and read aloud on live.	Consonant-only abbreviations usually pass through untranslated as meaningless letters.
ㅠㅠ	yuyu	Crying emoticon — sadness, or exaggerated mock-sadness.	Left as literal characters, so the emotional register of the sentence is lost.
헐	heol	"No way" / "whoa" — surprise, good or bad.	Often omitted, which flattens a reaction into a neutral statement.
레전드	rejendeu	"Legendary" — a moment fans will clip and re-share.	Passed through as "legend", losing the adjectival, moment-of-the-stream usage.
각	gak	A "setup" or a moment shaping up — as in "comeback 각", a comeback looks likely.	Literally "angle", which makes no sense in the sentence it appears in.
짤	jjal	An image or meme clip circulated by fans.	Frequently untranslated or replaced with an unrelated homophone.
먹방	meokbang	An eating broadcast — a stream where the host mainly eats and chats.	Sometimes rendered as "eating room", missing an established loanword that English already uses.
