I'm honestly glad that I've never been popular enough to be invited on a stag do, the majority of them seem like a nightmare. Thirty or so years ago it was usual to just go to a pub with your mates for a few drinks, now it's fashionable to have a whole programme of activities like go karting, going to football matches, tacky strip clubs, all under pressure to chip in financially for all this stuff and pretend like you're having fun with a bunch of random blokes you've probably never met. The phrase "forced jollity" comes to mind.
