💘입덕

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.

origin최애 became widely recognizable through Korean fandom and otaku-style communities where fans needed a compact way to name their top favorite member, character, or work. The exact first use is hard to verify, but by the 2000s–2010s it was common across idol fandom, web communities, and later mainstream social media. Today it works beyond fandom, as in 최애 음식, 최애 카페, or 최애템.

origin차애 combines 次, meaning next or second, with 愛, meaning love. It spread through Korean fandom language alongside 최애, especially in idol, anime, webtoon, and character fandoms; the exact first use is hard to pin down, so the year is approximate.

originThe expression likely formed naturally in Korean idol fandoms by combining the Koreanized English words “all” and “fan.” It became common as fans needed a quick way to distinguish group-wide supporters from solo fans, member stans, and more hostile 악개 behavior; the exact first use is unclear.

origin악개 is widely understood as a shortened form of 악성 개인팬, built from 악성 meaning malicious and 개인팬 meaning solo fan. It appears to have spread through online K-pop fandom spaces in the early 2010s, though the exact first use is hard to verify; today it is used critically to separate ordinary solo fans from fans who create hostility inside a group fandom.
