FNAS, short for Five Nights at Sonic's, is a fan-made horror series inspired by Five Nights at Freddy's, and Solar Switchup is one of its jumpscare variants shared through fan soundboards. The fifth version circulated as a short standalone clip, separate from full gameplay, which helped it travel beyond players who knew the original game. Like a classic FNAF jumpscare scream, it is now reused mainly as a reaction and editing sound, because its instant loud burst works even without the game context, keeping it useful for horror memes and short videos.
