Short for "Young Creator Crew," the title of a song by boy group CORTIS. Originally meaning "a group of young creators," it's now used to mean "trendy" or "in tune with current vibes." The opposite, "Neulkeukeu/Olkeukeu" (Old Creator Crew), emerged as self-deprecating humor among office workers in their 20s-30s joking "I'm not YCC anymore, I'm OCC." It spread from K-pop fandom during the song's February 2026 pre-release to mainstream variety show subtitles. Part of the appeal is that "creator crew" sounds like "keukeu" (ㅋㅋ), the Korean text for laughter.
