The word that gives the irish, and the college sports programs the Irish reputation for brawling. A donnybrook often takes place in a pub(bar) or on some occasions, the house of an Irish family. A donnybrook often involves heavy alcohol use, and anybody in the place the donnybrook happens. The end of a donnybrook usually results in missing teeth, lacerations to the head, scars, scrapes, and bruises to the body. If you ever hear of a donnybrook starting at the place you're in, either run, or participate and be prepared for all of the above fleshwounds the next morning.
A donnybrook is about to break out, it starts with two and multiplies rapidly.
