One of the biggest bands of the 70s is attempting to trademark a signal that looks strikingly similar to what University of Texas fans, students and alumni know as their own: the hook 'em horns sign.

According to the United States Patent and Trademark Office, KISS' Gene Simmons applied to claim the signal that involves extending the index, pinky finger upward and the thumb perpendicular, while the other fingers remain closed in a fist.

While the "rock on" symbol isn't exactly the same as the hook 'em sign -- it differs in thumb placement -- the trademark attempt is a little too close for comfort for UT President Greg Fenves.

Tweeting directly at Gene Simmons, Fenves said, "Sorry, @genesimmons, Longhorns have been doing 🤘 since the 50s — more than 20 years before KISS got going."

The short history lesson and polite clap back from Fenves were well received on Twitter, with over 1,000 retweets and 3,000 likes.

And like Fenves, Longhorn nation shouldn't be too concerned about trademark infringement. According to Hook', the symbol was created in 1955 and the University protects all of its trademarks.

Simmons' application is currently pending.
