Basuri is a name associated with loud pressure air horns commonly fitted to trucks, buses and auto rickshaws in India, where elaborate musical horns are part of road culture. Clips of the horn were shared online as a standalone sound effect because one blast is instantly recognisable and much louder than a standard car horn. It spread through prank videos, reaction edits and soundboards, and remains popular as shorthand for chaotic traffic, an aggressive warning, or someone announcing their arrival in the most dramatic way possible.
