n bachelor party. The groom’s pre-wedding lads’-night-out party. It generally involves drinking as much alcohol as possible and trying to do something embarrassing to the husband-to-be. This is great fun for all of the groom’s buddies, but less fun for the groom as he almost inevitably wakes up the next morning completely naked and tied to a lamppost somewhere in a foreign country. Brides secretly like stag nights because it gives them a good excuse for refusing to let their husbands see their friends again.
