What is another word for stag night?
Pronunciation: [stˈaɡ nˈa͡ɪt] (IPA) 
Stag nights are just one way to celebrate the groom's last night as a single man, but there are several other terms that people use interchangeably. These include 'bachelor party,' 'stag do,' and 'buck's party.' These terms all refer to the same event, but they're used differently in different countries, and they don't always have the same connotations. 'Stag night' is typically used in the UK and Ireland, whereas 'bachelor party' is more commonly used in the USA. 'Buck's party' is an Australian term, and 'stag do' is a more informal term that's used across the globe. Regardless of which term you use, the goal is the same - to give the groom-to-be a wild and memorable night before his big day.
