A bachelor party (also called a stag party, stag night (UK, Ireland, Canada, and NZ), bulls party (South Africa) or bucks party, bucks night (Australia)) is a party held for a bachelor shortly before he enters marriage, to make the most of his final opportunity to engage in activities a new wife might not approve of, or merely to spend time bonding with his male friends (often in his wedding party afterwards).
Tagline: "Shocking, Shameless, Sinful, Wicked. And the party hasn't even started." "A man's tradition every woman should know about."
