A stag and doe party, stag and drag party, hen and stag party, buck and doe party, or a jack and jill party is a party and fundraiser for an engaged couple.
In Canada, an event popular mostly in Manitoba or Ontario under various names to raise money for a couple who have not previously saved money for their future wedding plans or honeymoon. In Southern Ontario it may be called a stag and doe, or buck and doe, and in Northwestern Ontario it is called a shag. In Manitoba, this is often called a social or wedding social with less fundraising pressure than seen in Ontario.
The event is usually organized by the bridal party, but in some circumstances may also be held by the bride and groom before they are married, similar to a Jack & Jill. It acts as a fundraiser for the wedding. Guests purchase entrance tickets and are entertained by draws, food and drink, music and fun and games that they will pay for to participate in. It is not a combined stag night/bachelor party and bachelorette party, or engagement party, as the primary focus is to raise money for the engaged couple who have not saved for their wedding in advance, so their new life together is not started in debt.
The intent of a stag and doe party is specifically to make a profit.
Often, people who may not be close enough to the engaged couple to warrant an invitation to the wedding or reception (especially in the case of a small wedding), will be "tapped" to attend the stag and doe so as to be part of the overall wedding fundraising. Hosting a stag and doe party does not preclude the couple from participating in other wedding-related parties, such as a bridal shower, bachelor party, bachelorette party, and so on.
A popular stag and doe tradition is a toonie toss, which has guests toss toonies (C$2 coins) at a Texas mickey (3L) bottle of liquor. The toss runs for some time until the Toonie closest to the bottle without making contact wins the bottle.
