Stan Loona is a viral catchphrase and internet meme that originated within the fandom of the South Korean girl group LOONA. Beginning around 2017, fans known as Orbits began posting the phrase across social media platforms, most notably Twitter, often accompanying it with fancams or short performance clips. The phrase quickly transcended the K-pop community to become a ubiquitous piece of internet slang, used both as a genuine call to support the group and as an ironic, spam-like response to completely unrelated news, celebrity drama, or even tragic events. It represents a peak era of digital stanning culture where aggressive promotion became a form of comedic performance, eventually being referenced by mainstream celebrities and news outlets worldwide.
