The footage comes as Joshua recently moved to Loughborough to train with trainer Angel Fernandez ahead of his rematch against Oleksandr Usyk.
Walking through the campus of the university, the former heavyweight champion was met with heckles from a group of students, and Joshua didn't take too kindly to it.
In response the Brit took matters into his own hands and found a way into the residence of where the students lived to give them a lesson in respect.
In the video, you can hear Joshua telling the nervous looking students, "Remember you're running your mouth because when I bring people up here and I start cracking your glass jaws, none of you will like it.
"When your jaws start breaking and people start chasing you out of this uni, none of you will like it.
"Watch your mouths because you don't know who you're talking to sometimes. I know all that public eye bulls**t, I ain't into all that"
Fans of the Olympic 2012 gold medallist will be hoping he takes this rugged attitude into his rematch with Usyk.
With Joshua claiming that this is the first fight he's ever gone into with a specific game plan, it looks as though the linkup with new trainer Angel Fernandez could be a huge moment in his career.
Should Joshua become a three-time world champion, it could possibly set up an all-British clash against Tyson Fury. The fight would be for all of the heavyweight titles.
There hasn't been an undisputed champion in the heavyweight division since Lennox Lewis beat Evander Holyfield in 1999.
Bermane Stiverne spoke to Planet Sport and said Joshua would not stand a chance against Fury if they meet inside the ring despite claiming it would be one of the biggest fights in history.
It would be a good fight, it would sell of course. It would be the biggest fight ever since Tyson-Holyfield," said Stiverne.
"This is a fight that I don't believe Joshua would prevail on this one. But right now, the only thing that can beat Fury is Fury.
"His personality, his belief, I think he is who he is in and outside the ring," Stiverne said when asked about what makes Fury so good.
"I have a lot of heavyweight friends and the person you see on the camera or in the ring is not the same person you see in the gym or at home. I think Fury is the same wherever he goes, he's not just putting on a show for the TV but that's his everyday life," added Stiverne.
