The sound comes from Snapchat stories featuring Israeli singer Netta Barzilai and beauty creator James Charles improvising together over Rihanna's Rude Boy. Rather than a studio recording, it is a casual, off-the-cuff duet that fans clipped and shared online, especially within stan Twitter circles where its scatting and gibberish vocals became a running joke. Its appeal has lasted because it captures an unlikely celebrity pairing at its most unfiltered, and the short, chaotic exchange is easy to reuse in memes, edits and reaction videos.
