To put it another way, this occurred well before the wedding.
If the preparations required here are anything like the ones needed after the wedding has taken place, we are almost terrified to attend the reception. It’s possible that this is a once-in-a-lifetime chance for us, and we shouldn’t let it pass us by.
In case there was any confusion about what was happening, the bride was getting shot in the buttocks. The term “derriere” is not the most accessible word to spell, especially if you are still suffering from the humorous injuries that have followed you around like this couple is recovering from right now. Derriere is a French word meaning “buttocks.” There might have been a rowdy party before the wedding, or there might have been something altogether else. There aren’t very many party favors that come with a walking boot and a feeling of sickness in the box.
