Up until about 3:50 of the video, my reaction would have been to quietly ask the bartender not to serve them any more drinks, if he hadn't already decided that. Once the serviette stripper dance starts, venue staff would have escort Joke Glasses from the premesis.
Then I'd have the deejay play a slow dance, something that's a total buzz kill for goofing off. Was the deejay in on this? It can't be a coincidence that they were goofing off to "Can't Touch This".
Then I'd have some words with the videographer. He/she would no longer be filming these ridiculous antics, mostly consisting of really bad dancing. I would be furious to hire a videographer and have seven minutes of awful dancing, simply because that means the videographer filmed awful dancing for seven minutes. What a waste of time. Surely, there was something more interesting going on, like a grape in a fruit bowl sloooowly drying out.
I'm at five minutes... and this is so boring. I can't finish it. I'm going to fall asleep. I believe that their behaviour gets even worse, but even with the person wearing only a chair sash and a bra (or something) as a guest, I wouldn't have left.
As the bride, I wouldn't have posted the video simply because that's exactly what Joke Glasses would want. Therefore, I would not do it. I don't think it's rude to do so though.
