You don’t call Chris Christie fat and get away with it.

Staffers for the portly New Jersey governor were ordered to freeze out elected officials who offended their boss — including a county freeholder who called him a “fat f–k” in the wake of Hurricane Sandy, it emerged Wednesday at the Bridgegate trial.

The governor didn’t take the insult lightly, seething in a phone call to Monmouth County Freeholder John Curley: “Who the f–k do you think you are calling me a fat f–k? I am the governor of this state,” according to testimony given by Christopher Stark, a former community liaison with the Christie administration.

Christie told Curley he would “f–king destroy” him if he didn’t attend an upcoming Hurricane Sandy event with him, Stark said.

The bitterness began after Curley called up Stark and fumed, “Who does that fat f–k think he is? He has nothing but press conferences while we are out here doing the work.”

Former Christie deputy chief of staff Bill Stepien ordered Stark to stop talking to Curley, writing in an email, “Lose his #. We don’t talk to him anymore.”

Curley confirmed the heated exchange, saying he’d also called Christie a “fat motherf—er” during an event in Union Beach, NJ.

The freeholder, who said he’s since apologized, explained that he was “overwhelmed” at the time and “frustrated by Trenton’s response” to the devastation Sandy had wrought on his constituents.

“He lit into me with expletives like you wouldn’t believe. It was crazy,” Curley told The Post of his conversation with Christie.

Giving Christie’s adversaries the silent treatment was par for the course for officials who offended the governor, Stark said.

Elected officials who weren’t in Christie’s good graces were referred to internally as “hands-off” — and talking to them could land you in hot water, the ex-staffer said.

After one of Stark’s colleagues took some heat for reaching out to Fort Lee Mayor Mark Sokolich, Stark asked his boss for a “list of hands-off mayors,” he said.

“We don’t need a reason, but is it possible to get a list of hands off mayors,” Stark wrote in a text message to his former boss Christina Renna.

That message was sent in August 2013, just before Renna’s boss, Bridget Anne Kelly, sent an infamous email saying it was “time for some traffic problems in Fort Lee.”

Kelly and Bill Baroni, Christie’s top appointee at the Port Authority, are on trial, accused of orchestrating the George Washington Bridge lane closures to punish Sokolich for not endorsing the governor’s 2013 re-election.

Amid calls for his head from former rival Rob Astorino, Gov. Andrew Cuomo brushed off accusations that he’d agreed to help Christie cover up the scandal by playing along with a bogus report that would say the lane closures were for a traffic study.

“It didn’t happen,” Cuomo insisted Wednesday, adding that it’s “factually impossible.

“If there was a conversation where we said we would do a report that does X, you know how you would know? There would be a report.”

Bridgegate mastermind David Wildstein testified in court on Tuesday that Cuomo told Christie he wouldn’t challenge a phony report — but admitted Wednesday that he didn’t directly hear the conversations and didn’t know “for a fact” that they even took place.

Meanwhile, Westchester County Executive Astorino insisted on Wednesday that Cuomo and Christie “should resign their offices for the parts they played here.”
