Živio is a South Slavic toast used in Croatian, Serbian and Bosnian, roughly translating to cheers and long live, and it is shouted when drinks are raised for health, luck and celebration. Online the single-word shout has become a handy reaction sound because it is instantly understood even without translation, carrying a festive, communal energy. Creators reuse it in travel clips, wedding edits, sports celebrations and group chats, where a short burst of cheering says more than a longer speech would during a happy moment.
