#1 TOP DEFINITION
덕후 — a hardcore fan or obsessive enthusiast. Borrowed from the Japanese word 'otaku,' but adapted into Korean culture. A deokhu isn't just a casual fan — they are deeply invested, knowledgeable, and dedicated. In K-pop, a deokhu might own every album version, attend all tour stops in their region, and maintain detailed fan archives. The term is used affectionately within fan communities.
Example
“She's a true deokhu — her apartment has an entire room dedicated to SEVENTEEN merchandise and she's seen them live 14 times.”
