Short electric sounds like this one have become a staple of online video editing because they communicate a whole action in under a second. A brief motor buzz can stand in for a switch, a tool or a futuristic device without any explanation, which is why editors reach for it in memes, tutorials and short-form clips. Its appeal is practical rather than tied to one famous scene: it is clean, instantly recognisable as electrical, and short enough to sit under dialogue or between cuts without slowing the pace.
