A Maryland mom and dad are being blasted online for pulling a cruel prank on their son — which included cursing the young boy out and convincing him he had done something terribly wrong.

“Get your f–king a– up here!” the child’s mother shouts at the start of a 6½-minute video, which was posted to YouTube and shows the deranged stunt going down.

“What the f–k did you do?! What the f–k?!” she screams repeatedly, as her husband films.

“What the hell is that,” the diabolical dad says, panning out to a mess of strewn Uno cards and fake ink spilled everywhere.

“I didn’t do that!” the boy says, breaking down in tears and clutching his chest in fear.

“I swear to God I didn’t do that!” he explains frantically. “Mom and Dad, I didn’t do that! I swear!”

The father, identified by the Philly Voice as Mike Martin, of Damascus, Md., is a notorious prank puller who has posted a slew of similar videos to his YouTube page, dubbed “DaddyOFive.”

Together, he and his wife rule their family with a funny bone and an iron fist — even going so far as to force their kids to plug their social media accounts at the end of some of their clips.

The “Invisible Ink Prank” video has racked up more than 300,000 views since being shared last week. In it, the couple stages a fake spill on a bedroom carpet and pretends to blame it on their son, Cody, in retaliation for a prior mess he had made.

“And here you go with the f–king lying again,” his mom says, as the boy cowers in the corner.

“You did this before!”

Countless YouTube users posted negative comments about the video throughout the weekend after the footage popped up online — so much, in fact, that Martin was forced to remove it and make another video explaining that his son was fine.

“I’m getting all kinds of hate right now on all my social media,” he said in the video, titled “BLOCKING ALL THE HATERS!”

“A lot of people are really pissed off about this video because we’re yelling and the kids are crying and everything like that and apparently it’s upsetting a lot of people,” he said. “A lot of people apparently don’t get it … A lot of people don’t see the humor in it.”

Martin went on to explain that Cody and his other children were completely fine with the prank, despite the outrage.

“Was anybody traumatized?” his mom, “MommyOFive,” asks in the follow-up video.

“No!” the children reply.

“I don’t even know what that words mean, but no,” Cody adds.

While some social media users defended the prank — saying the Martins were simply having fun and acting like a typical, everyday family — most blasted them for taking things too far.

“How ANYONE could defend DaddyOFive is mind boggling. mental abuse is just as bad as phasyical abuse,” tweeted one person. “There’s a FINE line between being a father/authoritarian and being a straight up f–king a–hole.”

Another user wrote, “Just when I thought prank channels couldn’t get any worse, the daddyofive channel has hit a new low. Essentially just child abuse for profit.”

Some of the other pranks that DaddyOFive has pulled in the past have included breaking Cody’s Xbox into pieces — and giving him a new one soon after — and falsely telling him that he was being put up for adoption.

“We are a wild Bunch but still a very loving and close family regardless of what people are saying,” Martin explained Monday on Twitter.
