El Silbon, also spelled El Silbón, is a feared figure from Venezuelan and Colombian folklore, particularly the plains of Los Llanos, where his story has been told for generations. According to legend, he is the restless spirit of a young man condemned to wander forever, announcing himself with a distinctive whistle that sounds close when he is far away. The tale spread through oral storytelling, songs and later horror videos, and Spanish-speaking creators now use the whistle alone as a broma, or prank sound, to startle friends and open creepy clips.
