Team Fortress 2 is Valve's long-running team-based shooter, and its domination system gives players a persistent rival to chase: dominate the same opponent repeatedly and that opponent can claim revenge by taking you down. The Nemesis sound takes its name from that back-and-forth, and it has travelled beyond gameplay onto soundboards and short-form edits, where the tense build is shorthand for a grudge being settled. Its brevity and clear dramatic arc keep it useful years after TF2 became a staple of gaming meme culture.
