memedics

Refers to the phenomenon where NewJeans songs like "Hype Boy" turn into memes and spread virally -- the term names that viral-spread effect itself.

A dance challenge set to the chorus "도마도마 (catch it!)" of the Brazilian funk track "MENTE MÁ." Launched by RIIZE member Wonbin, it spread through China's Douyin before being re-imported back to Korea.

The practice of K-pop groups building an ongoing continuous storyline across their albums and music videos. "Universe lore" analysis videos have become their own content genre.

A K-pop group releasing a new album is called a "comeback"; the word has spread into everyday speech to mean simply "I'm back."

Korean transliteration of the English phrase "cheer up," used to encourage someone. Famous as a Twice song title; used as "cheer up 해봐" ("try to cheer up").

A coordinated effort where fans stream a song simultaneously at a set time to boost chart rankings; a core piece of K-pop fandom culture.

Short for "eumak bangsong" (music broadcast) — refers to weekly K-pop chart shows like Music Bank, as in "our song got #1 on the music show today."

A video shot by a fan focused on a single idol member — K-pop fancam culture went global and even coined the English loanword "fancam."

Someone skilled at everything — originally used for idols who could sing, dance, and act, now applied generally as praise for versatile people.

A worldbuilding term from SM Entertainment's idol-group lore, now also used sarcastically — saying "let's meet in the wilderness" mocks overly dramatic or unrealistic setups.

Entering a fandom for the first time; the opposite is "taldeok" (leaving a fandom). Commonly used in phrases like "ipdeok video" — the clip that got someone hooked.

BLACKPINK's Rosé released the song "APT.," inspired by the Korean drinking game "Apartment," and its Billboard success turned the drinking game itself into a global meme and challenge.

A Q&A format meme built from the lyrics of NewJeans' song "Hype Boy." Structured as "When [situation], what is it? Hype Boy-yo," it can be endlessly adapted to any scenario.

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.
