Neco Arc began as a feline parody of Arcueid Brunestud in Type-Moon's Tsukihime universe and became a recurring joke character in the Melty Blood fighting games, where her exaggerated voice and chaotic personality made her a fan favourite. As clips from those games spread through YouTube, TikTok and Discord soundboards, short Neco Arc vocals became shorthand for playful nonsense and sudden absurdity. The yamapika line is now shared mainly as a meme sound, reused because it is instantly recognisable to anime fans even without any context.
