Age of Empires II, released in 1999, included numbered chat taunts that let players send short voice lines to opponents and allies during multiplayer matches instead of typing messages. The English set became widely recognised among players because these lines were quick, distinctive and easy to trigger with a number key. As gameplay clips and strategy videos spread online, individual taunts were lifted out of matches and reused as reaction sounds. This Ahh remains useful because its meaning is instantly clear, a brief moment of surprise that fits almost any unexpected turn in a game or edit.
