Junkrat is the explosive-obsessed Australian hero from Blizzard's Overwatch, released in 2016, whose frag launcher and RIP-Tire made him a fan favourite for chaotic plays. 'Eita porra' is Brazilian Portuguese slang roughly meaning 'oh damn', a common outburst when something goes wrong. The clip lives on as a reaction sound in Brazilian gaming circles and meme soundboards, dropped over failed plays and unexpected explosions, in the same spirit as other shock exclamations. Its exact origin is unclear, which is typical of fast-spreading gaming memes.
