What began as a humorous shirtless tribute to a metal icon has transformed into a viral sensation, thanks to a Kentucky man and his innovative “tit-tar” skills.

How the ‘Tit-tar’ Began

Like many metal fans, Aaron Hartman, known online as Studmuffin Supreme, sought solace in music after the death of Ozzy Osbourne on July 22, 2025. He turned to music to find some light amid the darkness of that day’s news.

However, he discovered something far beyond temporary relief.

“I heard ‘Crazy Train’ come on and I started playing the drums on my stomach,” the 35-year-old explained. “I wasn’t wearing a shirt and I just started moving up to my man boobs.”

Hartman continued playing along with the song on his body, gradually incorporating more jiggle from his chest into each note.

Little did he know what he had created in that moment. A video of his shirtless performance was later uploaded to TikTok, where it quickly garnered thousands of views from people captivated by Hartman’s precision while playing along with the Ozzy classic.

The “tit-tar” was born.

From Slipknot Dances to ‘America’s Got Talent’

Hartman’s venture into “tit-tar” wasn’t his first experience with viral fame. Years earlier, he gained a TikTok following by dancing along (while wearing a shirt) to Slipknot’s “Before I Forget.”

The 15-second video also caught the attention of America’s Got Talent producers, who invited Hartman to perform on the NBC show.

“The first thing I said to them was ‘Are you guys desperate?'” recalled the Independence, Kentucky resident. “I really didn’t even think I would make it on stage, let alone be there for a full segment.”

Not only did they want him to come to California to recreate his viral dance, but they also requested that he perform in front of a crowd for two minutes while being critiqued by a celebrity panel of judges.

This might not seem like a long time, but Hartman found the entire experience rather exhausting, given his limited collection of dance moves and the fact that he had only created short videos for his Studmuffin Supreme social media accounts up until that point.

“I was kind of blanking out and staring into the crowd.”

Hartman continued thrusting his hips as Technotronic’s 1989 dance hit “Pump Up the Jam” blared throughout the Pasadena Civic Auditorium. One-by-one, each of the celebrity judges pressed their buzzers, indicating their disapproval with a big red X over the stage.

All but Heidi Klum voted for Hartman to be removed from the stage.

“The crowd was cheering and they were booing the judges that buzzed me out.”

Losing Weight and Improving His ‘Tit-Tar’

A lot has changed for Hartman since he introduced Studmuffin Supreme to a national television audience nearly two years ago. He has lost nearly 100 lbs. since the show and has worked hard to enhance his “tit-tar” skills.

“The more weight I’ve lost, the more confident I have felt in myself,” Hartman said regarding his weight-loss journey.

The progress is evident in the “tit-tar” videos where Hartman continues to refine his craft. He has added everything from vibratos to pinch harmonics to his performances.

“Once I learned that the jiggle effect made it funnier, I started incorporating those.”

Hartman has played the “tit-tar” along to songs by Iron Maiden, Megadeth, and his personal favorite, Metallica. He primarily records short clips at home, where his wife, Dandrea, often catches him mid-song on their security camera.

For fun, Dandrea will send footage from the security camera to Aaron while he is working on his next viral “tit-tar” hit.

“She will send me those and it just sounds like me slapping meat.”

Hartman hesitates to call himself a “tit-tar” expert, even though he may have spearheaded this topless musical movement. He has even received videos from others attempting their own “tit-tar” performances in search of feedback from him.

Hartman’s Studmuffin Supreme TikTok account has grown to more than 883,000 followers, with another 28,000 followers joining his Instagram. Most recently, Hartman started selling Tit-Tar Hero T-shirts as a playful nod to the Guitar Hero video game franchise, which he credits for honing his rhythm skills.

This is quite an achievement for someone who began all this by tapping along with “Crazy Train” on their belly while searching for a reason to smile after losing a metal icon.

“When I did the thing for Ozzy, it was just one and done; I thought,” Hartman reflected on his past year. “It was just to satisfy my need. I was just like, ‘This one is for Ozzy!'”
