When your biggest rival stumbles, you don't just watch—you pile on. That's exactly what happened after São Paulo's painful elimination from the Copa do Brasil this Wednesday (13), falling to Juventude in Caxias do Sul.

The Morumbi side's defeat sent social media into a frenzy, with rival fans seizing the moment to unleash a wave of taunts and memes. The sting was especially sharp because São Paulo had high hopes for this tournament, making the early exit a bitter pill to swallow.

Corinthians supporters, in particular, were quick to celebrate—and for good reason. The decisive goal came from Mandaca, a player known as "Son of Terrão," who scored in second-half stoppage time. The irony wasn't lost on anyone: Mandaca had left Juventude to sign with Internacional in 2024, adding an extra layer of drama to the moment.

From clever one-liners to full-blown celebrations, the reactions poured in as rivals reminded São Paulo that in football, no loss goes unpunished. Whether it's a friendly jab or a full roast, the message was clear: when your rival goes down, you make sure they know it.

For fans looking to gear up for the next match, remember that every game is a chance to show your colors—just make sure your team is on the winning side of the banter.
