Jet Set Radio is a Sega action game first released for the Dreamcast in 2000, built around a rollerblading street gang that tags rival turf across a stylised, futuristic Tokyo. Spraying graffiti is central to its gameplay, so the short aerosol hiss became one of its most recognisable in-game sounds. As retro gaming clips, speedruns and graffiti edits spread online, creators lifted the effect for short videos and memes, where it instantly signals tagging, rebellion and early 2000s game nostalgia without needing any dialogue.
