A resurfaced video of a man throwing a savage haymaker at a drunken barfly who groped his wife has gone viral, sparking a fierce debate about whether his use of force was appropriate in defending his spouse’s honor.

The undated security footage — which is at least a year old — shows a married couple getting ready to play a game of pool at a mostly empty bar.

As the husband racks the balls, his wife at the other end of the table is approached by a clearly intoxicated man in a red polo shirt and torn jeans, who appears to grab the woman’s rear-end before she shoos him away.

The husband saw the whole thing and, in a flash, furiously charged at the inebriate, delivering a devastating overhand punch to the perv’s face.

The force of the strike sent the creep, who is noticeably smaller in stature, crashing to the floor.

The wife attempted to get between the rivals before the knockout blow, but the enraged husband brushed her aside and appeared to accidentally knock the pool cue into her face, prompting her to press a hand to her cheek to see if she was cut.

Moments later, a member of the bar staff, possibly a bouncer, walked over to the husband and gestured that he had to leave.

The video has drawn a range of opinions online, from supporters who said they’d have done the same thing to detractors saying the husband took things too far.

“A haymaker against an inebriated opponent of much smaller stature? Nope. You confront the guy, you make him apologize, and you tell him to go home and sober up after he does. This is low-t behavior,” one X user wrote.

“This is how u end up in jail…some things just aren’t worth it imo…,” opined another.

“The dude is very insecure, even his woman tried to stop him, what if the other dude was bigger and stronger and sober??” a woman poster asked.

There were also plenty of commenters who thought the hubby was just defending his wife against unwanted contact from a stranger.

“That was a solid hit. Guess he will think twice before grabbing a woman again,” a supportive poster wrote.

“This is how a man handles business… This drunk idiot learned the hard way,” said another commenter who felt the lush got what he deserved.

“And since when does a guy grabbing a woman’s ass out of the blue not rate a fist to the jaw?” asked one responder surprised at the split opinion about the incident.

Some pointed out that a punch of that ferocity, or a collision of the man’s head with the barroom floor, could have turned fatal.

“Dude deserves it, but that punch could have killed him and it would be better to not go to prison for murder.”

None of the people involved in the incident have been identified. It was not immediately known if any charges were filed or where the bar was located.
