Jacket is the main playable character in Hotline Miami, a top-down action game released in 2012 by Dennaton Games and known for its animal masks, neon 1980s Miami setting and relentless pace. Small sounds like idle loops helped define its atmosphere, filling quiet moments between violent stages with unease. As clips and edits from the game circulated on forums, YouTube and soundboards, these minor audio details became recognisable to fans on their own. Jacket Idle 2 is now reused outside the game as a shorthand for tense waiting in gaming memes.
