The sound combines two online horror fandoms: Sonic.exe, the long-running creepypasta version of Sonic turned into a corrupted, menacing figure, and Sprunki, the fan-made Incredibox mod known for switching cute beatbox characters into a dark horror mode. Clips mixing the two circulate in fan animations, edits and soundboards, where a familiar game sound is twisted into something glitchy and wrong. It stays popular because the contrast is instant, even for viewers who do not know either source, and a few seconds is enough to signal parody horror.
