You see it everywhere. It’s on the giant screens at Coachella, in the front row of a Metallica concert, and probably in half the selfies on your camera roll. Someone raises their hand, folds down the middle and ring fingers, and leaves the index and pinky fingers standing tall. Most people call them "rock on" hand signs or "devil horns." But honestly, if you think this gesture is just about heavy metal, you’re missing about two thousand years of history.
The index and pinky finger sign—formally known as the corna—is one of those weirdly universal human symbols that means something totally different depending on which border you just crossed. In Austin, Texas, it’s a sports cheer. In Italy, it’s a nasty insult. In some parts of the world, it’s literally meant to keep the devil away.
It’s complicated.
Where the Index and Pinky Finger Sign Actually Came From
Forget the 1970s for a second. We have to go way back. The gesture has roots in ancient Hinduism and Buddhism, where it’s known as the Karana Mudra. If you look at ancient statues of the Buddha or various deities, you’ll often see this specific hand position. It wasn't about music or rebellion. It was a tool to expel demons and get rid of negative energy.
Then things got messy.

In Mediterranean cultures, specifically in places like Italy and Greece, the mano cornuta (horned hand) took on a protective, almost superstitious role. If you saw someone who looked like they were giving you the "evil eye," you’d flash the index and pinky finger sign toward the ground. It was like a spiritual shield. But—and this is a big "but"—if you pointed those same fingers directly at a man, you were basically calling him a cuckold. You were telling him his wife was cheating on him. Even today, doing this to a driver in Rome is a great way to start a fistfight.
The Ronnie James Dio Connection
We can’t talk about the rock-and-roll version of this gesture without mentioning Ronnie James Dio. Before he replaced Ozzy Osbourne in Black Sabbath in 1979, the "peace" sign was the go-to move for rock stars. But Ozzy had already claimed the V-sign as his brand. Dio needed something different.
He didn't invent it. He actually learned it from his Italian grandmother.
Dio often spoke about how his "nonna" used the index and pinky finger sign to ward off the malocchio (the evil eye). He started doing it on stage to connect with the fans, and it spread like wildfire. It became the shorthand for the entire heavy metal subculture. Interestingly, Gene Simmons from KISS once tried to trademark a similar version (with the thumb extended), but he eventually dropped the claim. It’s a good thing, too. You can’t really "own" a gesture that has been carved into stone temples for centuries.

The "Hook 'em Horns" Exception
If you’re in Austin, Texas, everything I just said about demons and metal music goes out the window. Since 1955, the index and pinky finger sign has been the official greeting of the University of Texas.
It started with a cheerleader named Harley Clark. He suggested the sign because it looked like the head of a longhorn bull. It’s probably the most wholesome use of the sign in existence. If you’re at a Longhorns game and you don't have your index and pinky fingers in the air, you’re the odd one out. This causes a lot of confusion when Texas fans travel abroad. There are legendary stories of UT fans accidentally insulting locals in Sicily or the Balkans by trying to show their school spirit at the wrong time.
Is the Thumb In or Out?
This is where people get really confused. There is a huge difference between the "Rock On" sign and the American Sign Language (ASL) sign for "I Love You."
- Rock On / Corna: Thumb is tucked over the middle and ring fingers.
- I Love You (ASL): Thumb is extended outward.
The ASL sign is a combination of the letters I, L, and Y. It’s meant to be a positive, affectionate message. However, because they look so similar from a distance, the two are constantly swapped. You’ll see pop stars and politicians using the "I Love You" sign when they probably think they’re being "edgy" and "rock and roll."
Why We Still Use It
The index and pinky finger sign persists because it’s a powerful tribal marker. When you raise those fingers at a show, you’re saying, "I’m part of this group." It’s a non-verbal handshake.
But it's also a lesson in cultural literacy. In 2005, President George W. Bush’s family made the "Hook 'em Horns" sign during his second inauguration. While Americans understood the Texas reference, newspapers in Norway and other parts of the world ran headlines wondering why the U.S. First Family was seemingly saluting Satan.

Actionable Takeaways for Using the Sign
If you're going to use the index and pinky finger sign, just keep these quick rules in mind to avoid an international incident:
- Check your thumb position. If you want to say "I love you," stick the thumb out. If you're at a Slayer concert, tuck it in.
- Know your geography. Avoid using the gesture in the Mediterranean, Brazil, or the Baltic states unless you are trying to start a confrontation. In those regions, it’s still a heavy insult regarding someone's romantic partner.
- Keep it high or low. Traditionally, pointing the fingers down is for protection (warding off evil), while pointing them up is for celebration or identification.
- Respect the mudra. If you’re in a spiritual or yoga setting, remember that the gesture is a Karana Mudra intended to clear the mind and space of negativity.
Understanding the index and pinky finger sign isn't just about trivia; it’s about navigating the subtle ways humans communicate without saying a word. Whether you’re a metalhead, a Longhorns fan, or just someone trying to ward off bad luck, you’re participating in a lineage of body language that spans millennia. Use it wisely.
