What is a stag do and why is it called that?

Short answer

A stag do is a celebration held for a man who is about to get married, usually with his close friends and family. The name comes from the stag, a male deer, which has long symbolised strength and masculinity in British culture.

A stag do is a gathering organised for the groom, or the person marrying, before the wedding. It is a chance to unwind, have fun and mark the move from single life to married life. Stag dos can be as simple as a pub crawl or as ambitious as a long weekend abroad with activities like paintball, golf or city breaks.

The word "stag" has been used to mean a man attending an event without a female partner since the 1800s. A "stag party" originally meant a gathering of men, and by the mid-1900s it became linked with pre-wedding celebrations. The stag, a male deer, adds a sense of tradition and virility.

Like hen dos, stag dos have evolved. They are now open to anyone marrying, regardless of gender, and many groups mix traditions or invent their own. The important thing is that the celebration suits the person at the centre of it.

Planning a stag do works best when the best man or organiser checks the groom's preferences first. Some grooms want a wild weekend; others want a quiet meal with old friends. Set a budget, agree dates early, and make sure everyone knows what to expect before they commit.
