The name Wahyu is a common Indonesian male name, and this stretched shout circulates on meme soundboards as a personalized callout rather than a quote from any known show, video or creator. No documented original source exists, so its spread comes from chat and stream culture, where Indonesian meme communities drop it to tag a friend named Wahyu. It sits alongside other elongated name-shout memes like FAAAH and FAHHH, and it endures because any group with a Wahyu can reuse it instantly.
