The sound is linked to Filian, a VTuber known for loud, hyperactive comedy and frequent vocal sound effects during streams. Clips of streamers imitating weapons and game noises circulate widely on soundboards and short video edits, where a recognisable voice matters more than a realistic recording. This ratatata impression fits that pattern, spreading as a reusable reaction for gaming and meme content. Its appeal is the human delivery behind the noise, which makes an ordinary machine gun effect feel personal, silly and instantly quotable for fans familiar with her style.
