The origin of this stretched Felix callout is not clearly documented, so its life online is mostly as a short shareable voice meme rather than a clip tied to a confirmed scene. It spreads through soundboards and chat shares where a name based greeting can be dropped in instantly, and its appeal rests on recognition of the elongated delivery rather than context. Because Felix is a common name, creators reuse it for friends and characters with that name, keeping the clip active as a light callout and reaction sound.
