Get this jerk a muzzle.

The belligerent man who went on a racist tirade aboard an L train over the weekend, wreaked subway havoc during another profanity-laced rant — in which he threatened to “bite” a commuter’s face off, a newly emerged video shows.

The undated cell phone clip, obtained by NBC New York, shows 36-year-old Paul Lawson antagonizing another straphanger on a train in Manhattan as he hangs onto an open case of Budweiser.

“Dude, you’re such a loser. I’ll kick the s–t out of you,” Lawson is heard rambling in the video to a man standing aboard the train.

The out-of-control rider continues, “Dude, call the police on me,” before he gets in the man’s face and says, “I’m not afraid. Why do you think I’m afraid? I’ve been to jail.”

That’s when Lawson threatens: “I’ll bite your f–king face off, dude.”

The victimized man then pushes Lawson away and Lawson retaliates, pushing him back as the other man exits the train.

“He started the fight!” Lawson shouts.

“You can’t push me and make it seem like I’m the aggressor,” he says after the man left the train. “I’ll stomp that dude out, I’ll beat his f—ing a–.”

Lawson made headlines this week after a video of him berating fellow straphangers and hurling racial slurs on an L train while drinking a can Lime-A-Rita went viral.

He can be heard on the damning video repeatedly shouting the N-word and boasting, “I talk s–t because I know I can,” during the bizarre Saturday incident that ended with him being kicked off the train by angry commuters and doused in hot soup.

After the incident, Lawson, in a now-deleted Facebook post, ranted that he was the victim of a “liberal mob.”

“I’m not that sorry. I feel bad I used that word but I was making a point,” he wrote in the post, according to Gothamist.
