Postal was released in 1997 as a controversial top-down shooter starring an unnamed man known as the Postal Dude, whose dry one-liners became part of the game's cult reputation. The phrase 'I regret nothing' captures that attitude in four words, so it travelled from game clips and forums into short-form video, where it works as a caption for reckless decisions. Its brevity and flat delivery have kept it useful long after the original game, especially in gaming montages and reaction edits.
