The sound comes from SMG4, the long running online parody series that reimagines Mario and other game characters in absurd sketch stories. This ASMR greeting riffs on the huge popularity of whisper videos and roleplay audio, putting Mario in a format he would never appear in officially. Clips from SMG4 are frequently cut into short sounds and shared across meme pages and editing communities, and this one survives because the premise is clear in seconds and works even without the original video context.
