The “Bagel Boss” guy is back at it again.

Video posted on Chris Morgan’s YouTube channel shows him getting into another tussle with a man nearly twice his size — this time at a casino.

“These girls called me up 2:30am begging me to come to the casino to hang out just to play f–king mind games and have their uncle try to start s–t with me!” wrote Morgan, 45, in the video description.

The 5-foot-tall terror can be seen kicking and cursing at his latest opponent, who tries brushing him off with one hand — while keeping a drink held tight in the other.

Morgan resorts to shin kicks and profanity throughout the 40-second scrum, and at one point gets socked in the face.

“Punch me again!” he tells the other man. “I’ll knock you right out.”

Morgan — who went viral last month following a meltdown at a Long Island Bagel Boss — posted the footage online Sunday. He is set to take on former Mets star Lenny Dykstra in a celebrity boxing match in Atlantic City.

Some social media users questioned whether the video was staged, or simply just Morgan getting in some practice rounds.

“Bagel Boss man please start taking your fight training seriously,” a person commented on YouTube.

“Got smacked and the old guy didn’t even spill his drink. Not one drop,” another said.

One user told Morgan, “Uh…. I think it’s time to hang up the gloves, the 15 minutes is over.”

The Long Island cleaning business owner has posted multiple videos of meltdowns that he’s had over the years. Some show him verbally attacking 7-Eleven workers, law enforcement and neighbors — all over his insecurities about his 5-foot stature.

Morgan’s Bagel Boss rant started after an encounter he had with one of the workers, who he thought was “giggling” at him.

“It’s about belittlement, what she was doing!” he yelled on video. “Giggling, all this crap! Being used by women, going on dates, they lie, say they like me and then use me for my money!”

The footage was viewed by thousands of people and supposedly changed Morgan’s luck with the ladies.

“I’m famous,” he told The Post. “I got girls hitting on me I don’t even know.”

Morgan was planning to press charges against his Bagel Boss foe, but it’s unclear what he will do about the casino incident. A security guard could be seen breaking the fight up, however, the video cuts off afterward.
