If you've been seeing a sudden influx of Bart profile pictures in certain college football-associated corners of the internet, you may have stumbled onto a brewing rivalry between Barts and Onions.

What began as a lighthearted way for people to display their B12 team affiliations turned into a trend where people share images of Bart fighting against humanoid onion creatures.

Here's how one X (former Twitter) user's goal to turn the world over to the "Bart" side resulted in Barstool's The Yak giving the Bart Cult a shoutout.
