LE SSERAFIM is a South Korean girl group that debuted in 2022, with Kim Chaewon as leader after her earlier time in IZ*ONE. Short clips of the members from interviews, variety appearances and livestreams are often cut into reaction sounds by K-pop fans, and this Panty exclamation spread in that format. Its appeal is less about context than Chaewon's delivery, so it survives as a standalone meme line shared in edits, comments and soundboards long after the original moment has been forgotten by most viewers.
