Definitions
British English for a bachelor party — the celebratory night out organised for a groom-to-be in the days before his wedding, traditionally involving his male friends, excessive drinking, and some degree of organised chaos. Stag nights range from quiet pub crawls to elaborate overseas trips, and the traditions around them have evolved considerably. The term 'stag' references the male deer, symbolising the last night of 'running free' before marriage.
The stag night got wildly out of hand somewhere between the third bar and the kebab shop at 2am.
