Fan Etiquette & Mistakes
- Privacy (Sasaeng): Never cross the line into
사생sasaeng (sasaeng) behavior. Following idols to their private residences or gym is not덕질deokjil; it is a crime. - Social Context: While
덕질deokjil is common, using it in a very formal job interview might sound too casual. Stick to취미chwimi (hobby) or팬으로서 응원하다paeneuroseo euwonhada (support as a fan). - Negative Nuance: Avoid using
팬질paenjil when talking to older people who might view fandom culture negatively; it can sometimes sound slightly belittling compared to the self-aware덕질deokjil.
