The chant comes from Hefty trash bag television advertising, where the repeated brand name was used to sell the bags as stronger than flimsier rivals. Its simple three-word rhythm made it easy to remember and easy to quote, so it survived long after the original commercials stopped airing regularly. Online, creators repurposed it as a reaction sound for anything that looks tough, heavy or hard to break, and its nostalgic advertising roots help it land instantly even for viewers who never saw the original ads.
