The A-10 Thunderbolt II, nicknamed the Warthog, became an internet staple for its GAU-8 cannon and the distinctive brrrt heard in games, films and viral plane clips. Farthog is a pun on that nickname, swapping the cannon for farts in the style of other crude edits like fart with reverb. The joke spread through meme soundboards and short gaming videos, where the familiar rhythm needs no setup. It remains popular because military footage, flight sims and shooter games still provide endless straight-faced footage to undermine.
