The melee unfolded Tuesday along St. Marks Place near Second Avenue when the driver — a 34-year-old man — argued with the still-unidentified skateboarder.

O’Hara, who exclusively talked to The Post, said he missed what sparked the street fight, but bystanders told him that the motorist had almost struck a skateboarder with dyed blonde hair and another man with the SUV.

The shouting match didn’t seem out-of-the-ordinary for a New York City street until the blond skater picked up the skateboard and smashed the SUV’s front windshield, O’Hara said Thursday.

“I’ve seen some crazy s–t in Florida, but I’ve never seen anyone once put a skateboard through (a window),” the Sunshine State native joked.

The video shot by O’Hara picks up moments after the skateboarder smashed the windshield, and shows him club the car two more times before throwing the board against it.

After the skateboard ricocheted to the sidewalk, the irate driver ran out and picked the board up, using it to land a body blow against its owner, the video shows.

The pair of pint-sized men — who O’Hara joked were “two 4-foot-6 dudes” — then awkwardly scuffle until the skateboarder throws the motorist to the ground, according to the video.

The skateboarder then picks up the board once more and smashes it over the driver’s head — all while a woman dressed in white, who was in the car, screams, “Stop,” the footage shows.

“Oh, my God,” O’Hara can be heard on the video as the sound of the board hitting the man’s head echoed.

The boarder then put the driver into a headlock as bystanders try to get them to break it up.

“He attacked me,” the skateboarder yells.

“He hit me with his car,” another man, who was apparently with the skateboarder when the fight started, screams at the onlookers.

The video ends with O’Hara walking around the damaged SUV and panning back to show the driver still being held in a headlock by the skateboarder.

O’Hara said he walked away at that point, opting to not let the unpleasantness ruin his “nice day.” He later shared the video on social media, where it racked up more than 3 million views on X alone.

NYPD cops responded to find that the driver lost consciousness while in the headlock, police said. Medics took him to Bellevue hospital in stable condition, officials said.

The skateboarder left before police arrived and no one has been arrested in the ongoing investigation, police said.

Many X commenters lambasted O’Hara for not trying to break up the fight, but he said that wasn’t his business.

“You’re clearly not from here,” he said to the haters.

“This is New York City, we mind our own business here… A stupid fight like that between two grown men, I’m not going to get involved in it.”

After learning the driver lost consciousness, O’Hara said he shouldn’t have opted to fight in the first place.

“Don’t get out of a car,” he said. “There’s no way in hell I would’ve gotten out of a car to fight somebody.”
