The 'Smart Fella, Fart Smella' meme is a prominent example of an internet spoonerism that relies on swapping the first letters of two words to create a ridiculous contrast. While the joke has roots in older playground humor, it saw a massive resurgence in the early 2020s within ironic meme circles and 'sigma' edit communities. It typically features a stoic or 'cool' character, like Joe Swanson from Family Guy or various anime protagonists, forcing the viewer to choose between being a 'smart fella' or the absurd alternative. The meme thrives on its low-brow humor and is often used to parody motivational posters or deep, philosophical inquiries.
