The title is Korean for Ryujin and Jingjing-i, Jingjing-i being the Korean name for Squidward Tentacles from SpongeBob SquarePants. Ryujin is a member of the South Korean girl group ITZY, so the pairing crosses K-pop fan culture with a long-running cartoon meme character. That mix explains why the clip circulates on Korean soundboards and in short fan edits, where Squidward is already a shorthand for complaining and bad moods. Its brevity keeps it useful as a repeatable reaction sound rather than a scene people quote in full.
