It appears President Donald Trump’s instincts about Lavar Ball were dead on.

Trump has been jousting with an unhinged Ball for a week after helping his son escape prison time, along with two other UCLA basketball teammates, busted for shoplifting while in China. Ball said he doesn’t feel like he needs to thank Trump for helping his son avoid prison, erupting a national backlash.

For newcomers to Ball’s shtick, acting like a bully is nothing new.

Just weeks ago, Ball savaged a female referee in a youth basketball game.

Ball went on a sexist tirade after he was ejected from an AAU game on this summer in Las Vegas, directing his frustration at a female official who was replaced mid-game when Ball attempted to pull his Big Baller Brand squad off the court until she was removed.

In explaining his frustration, Ball told multiple media outlets that the female referee had a “vendetta” and “needs to stay in her lane because she ain’t ready for this.”

Ball said of the female referee, who declined to comment: “She’s a woman who’s trying to act — I get that she’s trying to break into the referee thing. But just giving techs and calling fouls, that’s no way to do it. I know what she trying to say: ‘I gave LaVar, I gave him a tech, I’m strong.’ That ain’t got nothing to do with it. Just call the game.

“If you’re going to be qualified, you better be in shape, and you better know the game. And she’s bad on both of them. She’s not in shape, she’s not calling the game right, and she don’t understand, so now she’s trying to make a name for herself. So she’s walking around like, ‘I’m the only woman in here.’ Yeah, we get it, I don’t care if you a woman or a man or whatever, just be good at what you do.”
