The exact origin of this Kasumi scoff clip is unclear, as it comes from a user-uploaded soundboard with no credited source work or voice actress. Short scoff sounds like this one circulate widely as reaction memes, passed between soundboards, edit audios and meme compilations because they convey attitude in under two seconds. Its staying power comes from versatility: the scoff reads as annoyed, amused or done depending on context, so editors reuse it across roasts, storytimes and sarcastic commentary without it ever feeling tied to one fandom.
