Sasaeng fan

Sasaeng or sasaeng fan (Korean: 사생팬; Hanja: 私生팬; RR: sasaengpaen) is the South Korean term for an obsessive fan who invades the privacy of Korean idols, drama actors, or other public figures in the entertainment industry. One of the most notable activities associated with sasaeng fans is stalking. The term sasaeng comes from the Korean words sa (사; 私) meaning "private" and saeng (생; 生) meaning "life", in reference to the fans' intrusion into celebrities' private lives. According to the estimates of celebrity managers in the Korean media, popular Korean celebrities may have "between 500 and 1,000 sasaeng fans", and be actively followed by about 100 sasaeng fans every day.
