The sound comes from The Legend of Zelda: Breath of the Wild, released in 2017, where small forest spirits called Koroks hide throughout Hyrule and call out Yahaha when Link finds them. Each discovery rewards the player with a Korok Seed, so the sound became tied to finding something cleverly hidden. Clips of the moment spread through gameplay videos and short-form edits, where creators reused it as a shorthand for a surprise reveal. It has stayed popular because it is instantly recognisable, upbeat and tied to a satisfying in-game discovery.
