The 'brrrt' comes from the A-10 Thunderbolt II, the US close-air-support jet nicknamed the Warthog, whose nose-mounted GAU-8 Avenger fires 30mm rounds so fast the burst sounds like one long ripping roar. Footage of strafing runs turned that noise into a beloved internet meme in military and gaming circles, where brrrt became shorthand for overwhelming firepower. This version pairs it with a mocking laugh, a classic meme remix format that frames the cannon as the punchline to someone's bad decision.
