Kokeke is the Japanese-style rendering of a chicken's cluck, the short ko-ke-ke cackle a hen makes when startled. The exact recording behind this 0.7-second clip is undocumented, which is common for tiny reaction sounds passed around soundboards. Online it circulates as a pocket-sized comedy effect, the kind of clip editors keep handy for farm jokes, anime reaction memes and light roasts. It sits in the same family as other animal meme sounds like screaming sheep, trading on the instant silliness of a barnyard noise landing in a human moment.
