Payday 2 is a cooperative first person shooter about bank heists and police assaults, developed by Overkill Software and released in 2013. Its missions are filled with short shouted orders, warnings and taunts designed to be heard over gunfire, and players clipped many of those lines for soundboards. Big mistake circulated in that context as a compact taunt for moments when an opponent or a teammate overreaches. It remains popular because the wording is universally understood, needs no explanation of the game, and fits almost any failure.
