Wololo comes from Age of Empires II, the 1999 real-time strategy game by Ensemble Studios, where monks chant it while converting enemy soldiers and villagers to the player's side. The sound escaped the game through online matches, streams and meme edits, where players used it whenever someone switched allegiance or was persuaded to change their mind. Its short length, distinctive rhythm and instantly recognisable chant have kept it alive in gaming videos, reaction clips and short-form edits long after the original release, because it sums up conversion in a single word.
