⏸️활중

originThe expression likely spread through Korean online fan and otaku communities in the 2000s as a counterpart to 입덕, meaning entering a fandom. The exact first use is unclear, but it is now a standard fandom-culture term used across idol, anime, game, actor, and character fandoms.

originThe term comes from 자체 제작 콘텐츠, literally “self-produced content.” It spread widely as K-pop agencies and artists began using YouTube and other official channels to release regular web-variety episodes, vlogs, behind-the-scenes clips, and fan-focused videos outside traditional TV broadcasting. The exact first year is unclear, but it became especially common in fandom language in the late 2010s.

origin사녹 is a shortened form of 사전녹화, a broadcasting term for recording a segment before the official airtime. The exact first use is unclear, but the clipped form became especially visible in K-pop fandom and music-show culture as fans discussed pre-recording applications, attendance notices, and 후기 posts.

origin총공 comes from 총공격, meaning “all-out attack,” and was already used in online communities before becoming especially common in idol fandom coordination. The exact first use is unclear, but by the 2010s it was widely understood as a scheduled group push for streaming, voting, hashtags, searches, or comments.
