As short clips began circulating on soundboards, this brief fan recording became a reusable effect for creators who needed quick ambience or a visual gag about heat and airflow. Its popularity comes from its versatility, working in realistic scenes, animations and memes alike, and it remains common in edits where a single familiar household sound can set the location and mood in seconds.
