💘설렘사

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.

originIpdeok grew out of Korean online fandom vocabulary around the late 2000s, alongside words like 탈덕, 덕질, and 덕후. The exact first use is unclear, but it became common across idol fandoms, anime/game communities, drama fans, and social media whenever someone describes the moment they newly fall into a fandom.

origin덕통사고 likely spread through Korean idol, drama, animation, and online fandom spaces in the early 2010s. The phrase compares sudden 입덕 to being struck by 교통사고, so the exact first use is hard to pin down, but it remains a common way to describe an unexpected fandom crash.
