This sound is associated with Shamiko, the nickname of Yuko Yoshida from the anime series The Demon Girl Next Door. Online, the clip spread through anime meme pages, short edits and reaction videos because the rapid babbling sound is easy to loop and instantly reads as panic. It remains popular for creators who want a cute but frantic reaction audio, similar to other anime reaction sounds like Tuturu, especially in short-form posts where a one-second emotional punch matters.
