Team Fortress 2 launched in 2007 as Valve's class based team shooter, with Nathan Vetterlein voicing the Scout, its fast talking Boston runner. This line comes from the Scout's domination responses, the insult lines a class delivers after repeatedly killing the same opponent. Players ripped and shared the short taunts on soundboards, in machinima and later in short gaming edits, where a single line could stand in for the whole character. It survives because domination lines were endlessly quotable and this mom joke needs no setup or context to land.
