Neco-Arc Chaos comes from the Melty Blood fighting game series, which grew out of Type-Moon's Tsukihime universe, and the character appears in Melty Blood: Type Lumina as a playful, cat-eared parody fighter. Short voice lines like this one spread through fighting game clips, reaction videos and meme edits, where players reuse a single punchy announcement to mark an entrance or a comeback. Because the line is so short and instantly recognisable to fans, it works as a quick audio shorthand for chaos and confidence, keeping it in regular use long after its first appearances online.
