The clip comes from the numbered taunt system in the Age of Empires games, where players could trigger short voice lines during multiplayer matches instead of typing. This one was made for connection problems, a common issue in online strategy games where one slow player could hold up everyone else. As the taunts were ripped into soundboards and meme packs, blame your ISP spread beyond the game as a ready made reply to lag, buffering, and stuttering streams, and it is still used whenever a bad connection ruins a moment.
