A donnybrook is most widely known as it relates to hockey. When teams get into a bench clearing brawl with multiple players fighting it other the commentators refer to it as a 'donnybrook'
Last nights game between the Las Vegas Knights and the Colorado Avalanche turned into one hell of a donnybrook when both teams benches emptied!
