Team Fortress 2 is Valve's class based multiplayer shooter released in 2007, and the Spy is its French suit wearing mercenary built around disguises and backstabs. His voice lines became some of the most clipped sounds in gaming culture, shared through forums, YouTube poops and soundboards for years. This short your mother line survived because it captures his personality in less than a second, polite and superior even while insulting someone, making it a reusable reaction far beyond TF2 matches.
