Foudre is the French word for lightning, and this clip is used online as a generic thunder sound rather than a recording tied to one film, show or viral moment. Storm and thunder effects have long been a staple of video editing because they instantly signal danger, drama or a sudden change in weather without any dialogue. Creators searching for a short, punchy strike use clips like this for edits, pranks and reaction videos, where the familiar crack and rumble needs no explanation to be understood.
