Wololo comes from the monk unit in the original Age of Empires, where the chant became tied to the conversion mechanic. Among strategy game fans, it turned into one of the most memorable audio cues of the series and stayed popular through sequels, remasters, and online memes. The sound spread far beyond real-time strategy communities because its meaning is instantly clear: someone or something has been converted. That simple joke keeps it useful in reaction edits, gaming clips, and crossover memes years later.
