Junkrat is an Australian demolition hero in Blizzard's team shooter Overwatch, first released in 2016, and thanks, mate is one of his in-game voice lines that players can trigger during matches.

It remains popular because it works as a short, recognisable thank-you for streamers, editors and Overwatch fans, even for viewers who have never played the hero themselves.
