I think “asshole” was an apt descriptor. This douchey bully sounds like if comedian Bill Burr had a ragey, unfunny brother.
From the video description
Attorney Christopher Kirby goes into a meltdown in the East Ramapo parking lot. Threatening to fight, and then goes into a profanity laced tirade. Board Vice-President Yonah Rothman tries to keep the unprofessional attorney in check.
This is what sparked the parking lot shenanigans. I can’t believe the school board members just sat there like spineless cowards while their law monkey was flinging his poo. What a disgrace.
