Team Fortress 2, released by Valve in 2007, gives each class specific domination lines when one player repeatedly beats the same opponent. The Soldier has a full set aimed at the Demoman, playing on their rivalry and the Demoman's Scottish identity. Clips of these lines spread through YouTube poops, Source Filmmaker animations and gaming soundboards, where short voice bites became reusable reactions. This one stayed popular because it is specific, quotable and tied to a real in game achievement rather than a random taunt.
