The sound comes from The Elder Scrolls IV: Oblivion, released by Bethesda in 2006 and famous for its stiff NPC conversations and radiant dialogue system. Short clips of characters repeating odd syllables were clipped and reposted on YouTube and meme pages, where the nininini loop stood out for its rhythm. It spread as a shorthand for awkward, broken or endlessly looping game dialogue, and it remains popular because modern RPG and AI voice memes still use Oblivion as the reference point for uncanny conversations.
