But I recently learned that it was so named because the father of said bride was likely to be so opposed to the shame of a daughter who would dare to fornicate before marriage, that he would resort to threatening to use a shotgun on the young man responsible, to obtain a marriage proposal. As in: "You better bloody make an honest woman of her or I will shoot you in the head with this here shot gun". It makes much more sense that way. How did I not know this?
Now days any marriage that seems to happen quickly is assumed to be because of an unplanned pregnancy and then coined a "shotgun" wedding. But realistically, these days most fathers would be more like "Oh god, please don't propose to her cus then I'll be expected to pay for the bloody wedding! Just buy a house and have a kid, that's commitment enough, surely!"
I used to think romance was dead in this post millennium world, but I don't really think it was that common to begin with. What we thought was our parents being romantic by getting married so young, was really just a woopsie, a death threat and their parents' attempt at saving face at church on Sunday. Super romantic.
One thing that will never die though, is pre-marital lust. And really, it is much more fun when it's a little bit bad isn't it?
