The stag do has been around for centuries - some think it originated around the time of the Spartans. I wonder, then, what that noble warrior race that has become part of time immemorial would think if they set eyes on the sordid shenanigans that us modern folk get up to. Or what they would make of the term 'banter'. So guys, please. Cease with the uncouthness. If you are selected as a best man, act as one. And follow this gentleman's guide to the stag do.
