Mamma knows best.

A California man lost his cool on a long line at a casino gas station in Riverside County, only to be rescued by his mommy before cops swooped.

Viral video shared to Instagram on Tuesday shows the man, wearing a “That’s what I do, I fix stuff and I know things” t-shirt, throwing an obscene tantrum, cursing out another driver and blocking the gas station pumps.

The clip racked up over 3 million views and 20,000 comments — none of which supported the “man baby.”

“He’s such a baby his mommy had to come and get him,” one commenter wrote.

According to the video’s caption, the recent incident took place at a gas station near the Agua Caliente Casino in Rancho Mirage.

The man recording, who says his children were in his car at the time, detailed the situation in the post’s caption.

“First off this dude was waiting at a different PUMP, to be specific the one behind the one I parked at. He was waved down by security and honked at by others around that the pump in front of the pump he was waiting for was open for 8-10mins before,” he wrote.

“He decided to not go to the open pump and when I did he then decided to go around the guy he was waiting for and park in front of the guy he was waiting for.”

“I had enough time to park, get off, pay for the gas and then proceed to start pumping when he then came and pulled the pump out, I started to record after, when I noticed him causing a scene,” the man continued.

The clip shows the man crossing his arms, childishly blocking access to the pump. When the man recording asks him to move from in front of the pump, he refuses, cursing him out.

“You don’t know how a fucking line works? This is a fucking line!” the man shouts.

Halfway through the video, the man’s mother appears, stroking his crossed arms in an attempt to calm him down.

“I’m his mom,” the woman says, after the man recording confuses her for her son’s “lady.”

When the doting mother warns the man that the police may arrest him, he shoots back “They ain’t gonna arrest me!”

Commenters mocked the mature man’s mother stepping in to soothe him.

“That little growl when his mom told him to go back, I’m surprised he didn’t do the light up skechers run back to the truck,” another commenter said.

“His momma been letting him act this way his whole life. She never disciplined him,” a third commenter wrote.

When the man recording asks a security guard off to call the police, the tantrum-thrower lunges towards him, grunts, and stomps back into his car. The man blares his horn for over a minute while flashing his middle finger.

“After this video ended with him honking I then proceeded with my life but had to wait after pumping gas to talk to the sheriffs that arrived to ask me what happened and if I wanted to press charges,” the man recording wrote.
