The line comes from Shenmue, Sega's 1999 Dreamcast adventure created by Yu Suzuki and starring Ryo Hazuki in Yokosuka, Japan. Its English dub became famous online for stiff, repetitive NPC replies when Ryo questioned locals during his investigation. Clips of those exchanges spread on forums and video sites as examples of awkward early voice acting, and short extracts were later shared as reaction sounds. This particular dismissal survived because it works outside the game, giving gamers a recognisable, deadpan way to end any interaction quickly.
