Who tha hell cares circulates online as a short meme reaction clip, shared in soundboards and short-form videos rather than tied to a single famous scene that can be reliably identified. Its spelling keeps the informal tha from the original upload, which is how many listeners search for it. The line spread because it fits almost any moment of exaggerated concern, from gaming arguments to celebrity gossip, and creators reuse it as a quick shutdown. Its staying power comes from that flexibility, offering an instantly understood shrug in audio form.
