Taunt 31 comes from Age of Empires II, released in 1999, where players could trigger numbered voice commands by typing them in chat during multiplayer matches. The system let allies coordinate without voice chat, asking for food, wood, gold or military help. Attack an enemy now became a staple aggressive call because it was direct and easy to spam. The taunts later spread through forums, videos and soundboards, and remain a nostalgic shorthand for old school real time strategy culture online today.
