Team Fortress 2, Valve's team-based multiplayer shooter released in 2007, gave its nine cartoon mercenaries hundreds of shouted voice lines, many of which became gaming memes on their own. Short reaction lines like this one thrived because they fit anywhere a plan goes wrong, and 'This is bad' joined a wave of TF2 one-liners circulating in fail compilations, edits and soundboards. Its staying power comes from the game's stylised comedy and a line that works for every genre of video, not just gameplay.
