The line comes from Meet the Heavy, one of Valve's short character trailers for Team Fortress 2 released in 2007 to introduce the Heavy Weapons Guy. In the video he cradles his minigun Sasha and warns that it costs four hundred thousand dollars to fire her for twelve seconds, before erupting at an unseen touch. Clips of the moment were later ripped and shared on forums, YouTube edits and soundboards, where the single angry question became a standalone reaction for anyone guarding a favourite item.
