The Spanish title translates to man singing with a leaf, which describes the entire joke in a few words. Leaf playing is a long-standing folk practice where a leaf held to the lips vibrates like a reed, and short clips of street or home performers doing it circulate widely as meme sounds online. This five-second version spread because the performance is brief, recognizable, and easy to drop into unrelated videos. Creators reuse it whenever a scene needs an intentionally cheap, improvised musical payoff instead of a polished soundtrack.
