Meet the Spy comes from Valve's Team Fortress 2 promotional short of the same name, released in 2009 as part of the game's Meet the Team series. The Spy became one of TF2's most quoted characters, and clips from this short spread widely through YouTube edits, gaming compilations and meme culture. The sound still shows up because it is instantly recognizable to TF2 fans and fits any scene built around deception, disguise or a dramatic reveal. Similar gaming reaction sounds include Enemy Spotted.
