Papucho comes from Spanish slang used in parts of Latin America as a teasing, affectionate word for a good looking man, similar to calling someone a hunk. The clip spread as a short soundboard and meme audio rather than as part of a widely documented song or show, which is why its exact recording origin is unclear. Online, creators reuse the single word as a ready made joke for entrances, thirst trap parodies and overconfident characters, and its meaning is understood even by viewers who do not speak Spanish because the tone does the work.
