Mathew Chill circulates as a user shared gaming sound tagged with Matt, Dota and Dota 2, which points to its roots in that community rather than a film or song release. The clip is only about one and a half seconds long, so it spread the way other short reaction sounds do, through soundboards, stream decks and quick edits shared between players. Its appeal stays in the name itself, turning a simple chill moment into a recognizable in joke for Dota fans who need a fast calm down button.
