“Wololo” is the battle cry of the Priest unit featured in the 1997 historical real-time strategy game Age of Empires. Due to its association with the Priest’s mystical ability to assume control of an opponent’s unit through conversion, the sound effect has gained notoriety among the fans as one of the most dreaded stock lines from the game. Online, the phonetic transcription of the chant is used as a taunt and an interrupter, which in turn prompts visual responses that indicate a switch of color between red and blue.
