Baseball players arriving at spring training this year have found themselves at the center of an unavoidable cultural phenomenon. Those wearing jersey No. 67 have become instant targets of the viral six-seven craze sweeping social media and playgrounds alike.

Of the 30 MLB teams, 25 have a player wearing No. 67 in camp. The trend traces to rapper Skrilla's single "Doot Doot (6 7)," released roughly a year ago, which evolved from an NBA highlight backdrop into a TikTok dance sensation and eventually a global cultural fixture. Dictionary.com named it word of the year in 2025 despite it not technically being a word.

Texas Rangers reliever Jacob Latz, who has worn 67 since 2014, has lived the phenomenon firsthand.

"Everyone I come across does that to me," Latz said, demonstrating the signature palms-up hand motion. "A lot of kids have started to follow me on social media. What's funny is a lot of older people are mentioning it to me too now. It's not just the younger generation."

Royals All-Star pitcher Seth Lugo, a longtime 67 wearer, discovered the trend's reach at a playground last October when a child had written the number on her hand.

"I was like, 'Hey you got my jersey number,'" Lugo recalled. "A few minutes later, she started chanting it. I was like, 'Why are you doing that?' And she said, 'This isn't you. This is something else.'"

Reactions among players have been mixed. Giants reliever Keaton Winn requested a number change this offseason after growing tired of the unwanted recognition, only to remain stuck with 67 after a veteran signing took his preferred replacement.

"A little annoying," Winn said. "I don't know what it means either."

Detroit Tigers closer Kyle Finnegan returned to 67 this season at his 14-year-old daughter's request. Chicago White Sox minor league pitcher Duncan Davitt learned of his assignment only when he found the number on his locker cubby at spring training.

"I think the point is that there is no point," Davitt said. "To be honest, I don't really get the craze of it. It's a thing, I guess."

The White Sox are capitalizing with a six-seven-themed bobblehead giveaway. Los Angeles Dodgers ace Blake Snell performed the signature hand gesture from a World Series parade float to thunderous crowd response. In-N-Out, meanwhile, discontinued announcements of order number 67 after the call repeatedly disrupted restaurant operations.

Whether the trend has staying power remains uncertain. For now, anyone wearing those two digits on their back has become an accidental celebrity, whether they want to be or not.
