The 'BRRRT' meme centers on the distinct, low-frequency sound of the GAU-8 Avenger 30mm rotary cannon mounted on the Fairchild Republic A-10 Thunderbolt II, affectionately known as the Warthog. Because the gun fires at such a high rate, the sound of the rounds often reaches the target before the sound of the firing itself, resulting in a terrifying mechanical 'fart' sound that has become legendary in military history. On the internet, BRRRT has evolved into a symbol of overwhelming force and absolute problem-solving, frequently paired with the 'Haha, plane go brrr' format or used to represent a loud, definitive end to any argument, obstacle, or inconvenient target.
