Hooray is one of the oldest and most recognisable cheers in English, used for generations to mark approval, relief and shared joy. In short form video and meme editing, brief hooray clips became popular because they deliver that reaction in about two seconds without needing dialogue or context. This version is shared on soundboards as a quick reaction button, pressed for announcements, unboxings, correct answers and lucky outcomes. Its appeal is its universality: almost any audience understands the meaning instantly, even when the moment being celebrated is deliberately trivial or ironic.
