The 'Wololo' meme originates from the 1997 real-time strategy game Age of Empires, specifically the sound effect made by the Priest unit when attempting to convert enemy units to the player's side. Visually represented by a priest in robes waving a staff, the conversion process causes the unit's clothing color to change—most famously from red to blue—signifying a change in allegiance. In internet culture, 'Wololo' has become shorthand for a sudden, often nonsensical shift in opinion, loyalty, or preference. It is frequently used to mock people who instantly flip their stance on an issue or to represent the persuasive power of a persuasive but simple argument.
