Airhorns have long been used at sports events, parties and in DJ drops to signal excitement, and their loud, unmistakable blast made them a natural fit for online humour.

The airhorn bomb version now circulates widely on soundboards and in short-form videos, where its instant, over-the-top impact works without any setup or explanation.
