Heavy is one of the nine playable classes in Team Fortress 2, Valve's team-based shooter first released in 2007, and his loud, heavily accented voice lines have long been reused as jokes outside the game. This run run clip circulates on soundboards and in short gaming edits, where its urgency works even for viewers who have never played TF2. Like the RUN vine effect, it functions as a quick audio punchline for movement, panic and overconfidence, which is why editors keep returning to it years after the game's peak.
