The sound comes from a routine by Cuban comedian Alvarez Guedes, whose rapid-fire insult comedy made the me cago en el arbolito line a familiar catchphrase in Spanish-language humour. Shared as a short clip, it spread through meme pages and messaging apps as a ready-made angry reaction, and it stays in use because the exaggerated delivery is instantly recognisable even to listeners who only know the punchline. Its short length makes it easy to drop into edits, dubs and voice notes without losing the joke.
