Tim Walz | Fox News

Tim Walz committed a fumble on Sunday.

The Minnesota governor, a former high school defensive line coach, was widely mocked for misusing a common football term after livestreaming himself playing video games.

Walz played the latest installment of the Madden video game series on Twitch with Rep. Alexandra Ocasio-Cortez, D-N.Y., to appeal to young male voters just days before the election. During the game, both Democrats urged voters to support Vice President Kamala Harris' bid for the White House.

“And we both know that if you take the time to create a playbook, you will use it,” Walz also wrote.

The post was later deleted, but critics quickly spotted the error.

Republican vice presidential candidate Sen. JD Vance of Ohio pointed out the difference between a pick 6 and offensive plays.

“You don’t run a pick-six, you run the West Coast offense or the spread offense,” Vance said at a campaign event. “I realized that I think I know more about football than Tim Walz, even though they say Tim Walz was a football coach. And that's appropriate because I think my vice president, Donald J. Trump, knows more about working at McDonald's than Kamala Harris.

“AOC can run a mean Pick 6 – and I can give an audible on a play. And they wonder why they can’t get men to vote for this ticket,” one X user wrote.

“Tampon Tim is such an idiot. You'd think a so-called football coach would know not to do a pick 6!” wrote the Trump campaign's “War Room” account.

“Are we sure Tim Walz has even seen a football game, let alone coached a team?” wrote another user.

“I'm not sure Kamala ever worked at McDonald's, and now I'm not sure Walz ever coached football,” wrote another.
