Age of Empires II is a real-time strategy game released in 1999 by Ensemble Studios, where monks are specialised units that can heal allies and convert enemies. The conversion mechanic builds on the priest chant from the original Age of Empires, often nicknamed wololo by fans. Online, that chant and the converted cue became shorthand for brainwashing, persuasion, and sudden loyalty changes. Clips, remixes, and gaming edits have kept it in circulation for decades, making it one of the most quoted sounds from classic PC strategy gaming.
