Team Fortress 2 is Valve's free-to-play, team-based multiplayer shooter, first released in 2007, and the Engineer is one of its nine playable classes, known for building Sentry Guns, Dispensers and Teleporters. His voice lines, performed with a relaxed Texan accent, became a familiar part of the game's humour and personality. Short clips like this one spread through TF2 gameplay videos, memes and soundboards, where players reuse them to signal a completed build or a well-placed defence. Because the game has remained popular for years, the line is still recognised instantly by fans.
