Buck's party is a term used in Australia and New Zealand to refer to a bachelor party or stag party for men. However, there are several other synonyms for this term, such as stag night, bachelor party, groom's night out, bachelor's night, boys' night out, and male bonding session. Each of these terms suggests an evening or a night of festivities, typically reserved for the groom or the male members of the wedding party. Whatever the name, the event is typically associated with having fun, celebrating the groom's final moments of single life, and creating memories with the boys before the big day.
