The exact original recording behind this clip is not widely documented, so it circulates mainly as a standalone Indonesian meme sound shared between friends. The phrase woi is a common informal way to call someone loudly, and pairing it with the name Bayu turned a simple shout into a reusable scolding joke. It spread through short videos and chat audios where any mistake could be answered with the same angry call, even when nobody involved was actually named Bayu, which helped it stay useful beyond its first context.
