While kicking off his new headlining Sundown Heaven Town Tour in California last week, Tim McGraw called out a group of rowdy fans who were exchanging words during his performance of a new song, “Keep On Truckin’.” During an instrumental break, Tim was shaking his head and mouthing “Stupid!” repeatedly.

As the music wrapped, Tim took to the microphone, saying: “Let me tell you something . . . if you stupid son of a b#%!s don’t stop trying to fight . . .. Don’t be an idiot . . . you’ve got a kid right here. Come on! You’re a grown man; don’t be an idiot.

“And that goes for you, too,” he added, pointing to another set of fans. “It’s country music, man! We’re having fun. We all paid good money, and we all work hard, just enjoy yourself. Shake hands, apologize and have a good time.”
