With no credited singer, source song or original video attached to this clip, its history is mainly in how it circulates as a reusable meme audio. The title users give it simply transcribes the vowels they hear, which is how it gets found and reshared on soundboards. It sits alongside other goofy ahh sounds built from short, wordless vocal noises that editors can drop into almost any scene. Its appeal is its flexibility, since the same oo melody can read as happy, lost, sleepy or sarcastic depending on the image placed over it.
