This clip belongs to Japan's long-running Inmu meme culture, built around Manatsu no Yo no Inmu, an early-2000s video that became a staple of Nico Nico Douga parody and slang like '例のアレ'. Within that scene, short horror-styled edits repurpose ominous stings for 'appearance' gags, where a character suddenly shows up. The format spread through MAD movies, game edits and TikTok-style meme cuts. It endures because the mix of dread and in-joke lets creators fake a jumpscare without needing real horror footage.
