You’ve heard it. If you’ve spent more than five minutes on MMA Twitter or scrolled through UFC TikTok lately, you’ve definitely heard it. That high-pitched, rhythmic, slightly chaotic screech that sounds like a cross between a bird call and a victory lap.
Chiwiwis!
It’s the Raul Rosas Jr meme that took over the combat sports world practically overnight. But if you’re sitting there wondering if you missed a secret meeting or if the internet has finally just broken, don’t worry. You’re not alone. Honestly, even the people screaming it at the top of their lungs at UFC events didn't really know what it meant at first.
Raul Rosas Jr., the youngest fighter to ever sign with the UFC, didn't just bring elite grappling to the Octagon. He brought a catchphrase that became a cultural phenomenon within the MMA community.
Where did Chiwiwis actually come from?
Most memes are manufactured by marketing teams or born from some embarrassing viral moment. This wasn’t that. The Raul Rosas Jr meme is actually way more wholesome—if you consider screaming at your friends wholesome.
Rosas Jr. explained that "Chiwiwis" isn't some ancient Mexican slang or a tactical code. It’s an inside joke. Basically, he was training at high altitude in Mexico’s Centro Ceremonial Otomí, preparing for a fight. There’s no cell service up there. No Netflix. Just training and, apparently, a lot of ping pong.
One of his close friends—someone he considers a brother—started saying it whenever he’d win a game or whenever they were just messing around. It was a word of pure hype. Rosas liked the energy, it stuck in his brain, and he decided to unleash it on the world during a post-fight interview.
It was impulsive. He didn't plan it. But the second it hit the microphone, the internet grabbed it and ran.
The meme that conquered the Sphere
There is a big difference between a funny video and a movement. We saw that shift at UFC 306, the massive "Noche UFC" event at the Sphere in Las Vegas.
Thousands of fans weren't just cheering for "El Niño Problemo." They were chanting "Chiwiwis" in unison. Imagine being a world-class athlete in the middle of a high-stakes cage fight and hearing a made-up word from a ping pong game being roared back at you by 20,000 people.
It’s kind of absurd. Actually, it’s completely absurd. But that’s why it works.
The Raul Rosas Jr meme represents a shift in how fans connect with fighters. It’s not just about blood and guts anymore; it’s about personality. Rosas is a kid. He’s Gen Z. He talks like his fans talk, and he’s not afraid to be a little weird on the mic.
Why the internet loves to troll (and support) Raul
Let’s be real for a second. The UFC community can be... intense. When Rosas first arrived, the memes weren't all "Chiwiwis" and rainbows.
Because of his unique look and his extreme confidence at such a young age (he debuted at 17), he became a target for "The MMA Underground" and Reddit trolls. People made memes about his face, his age, and his bold claims about becoming a three-division champion.
Then he lost to Christian Rodriguez. The "hype train" memes were everywhere. People love to see a phenom fail.
But Rosas did something smart. He leaned into the fun. Instead of getting defensive or disappearing, he doubled down on being himself. He started the "Chiwiwis" thing, he sold the t-shirts, and he stayed active. He turned the mockery into a brand.
Now, when you see a Raul Rosas Jr meme, it’s usually someone celebrating a win or just using the catchphrase to express excitement about literally anything.
- Got a promotion at work? Chiwiwis.
- Found a twenty-dollar bill in your jeans? Chiwiwis.
- Your parlay actually hit? Definitely Chiwiwis.
The "Former Mexican" and other weird variations
If you dig deep into the Reddit threads, you’ll find some truly bizarre stuff. There was a viral clip where Dana White was confused by an interviewer referring to Rosas as a "former Mexican."
It was a total linguistic mix-up, but in the world of MMA memes, that’s gold.
Then there are the "unintentionally funny" moments. Rosas often gives interviews that feel like a high schooler who just won a state wrestling title, which—to be fair—is basically what he is, just on a global scale.
He recently made headlines for a "prank gone wrong" where he ended up choking out a YouTuber named Opto (Aris Sureni) from Topnotch Idiots. The YouTuber tried to "bully" him on a treadmill as a joke, and Rosas... well, he reacted like a professional fighter. The footage of the prankster going unconscious while Rosas looks mildly annoyed is peak meme material.
How to use the meme (The right way)
If you want to join the "Chiwiwis" army, you have to understand the vibe. It’s not a serious word. You don't use it when you're angry.
It’s a "word of excitement," as Rosas puts it. It’s what you say when you’re "cotorreando" (hanging out/joking around) with your friends.
The Raul Rosas Jr meme succeeds because it’s authentic. It wasn't a catchphrase he sat down and wrote with a publicist. It’s just a kid having fun while he punches people for a living.
What most people get wrong
People think "Chiwiwis" means something specific in Spanish. It doesn't.
If you ask a Spanish speaker from Spain or Argentina what it means, they’ll look at you like you have two heads. It’s hyper-niche. It’s "friend-group" language that just happened to go global.
What’s next for El Niño Problemo?
Rosas is still incredibly young. He’s going to be in the UFC for a long time, which means the memes are only going to evolve.
We’ve already seen the "Braided Raul Rosas" meme (a specific look he had for a fight) and the "Chiwiwis" t-shirt line. As he moves up the rankings, the pressure will increase, but for now, he’s the king of the MMA social media landscape.
If you’re looking to keep up with the latest iterations, keep an eye on his post-fight speeches. He usually drops a new "Chiwiwis" or a variation of it every time he gets the win bonus.
Your next steps for Chiwiwis mastery:
- Watch the UFC 306 highlights: You need to hear the crowd chant it to truly understand the scale of the meme.
- Check his Instagram (@raulrosasjr): He’s surprisingly good at engaging with the fans and keeping the joke alive without it feeling forced.
- Don't overthink it: If you're trying to find a deep, philosophical meaning behind the word, you've already lost. Just scream it when something good happens.
