A knobstick wedding is a type of wedding that used to happen in old days when a couple was unable to afford an actual wedding ceremony. Instead, they would simply declare themselves married while holding onto a knobstick, which is a kind of long wooden stick that has a knob on one end.
The couple would stand together, and each of them would grasp the knob on the end of the stick with one hand. By doing this, they would be making a formal declaration that they were now husband and wife.
Knobstick weddings were often done secretly, because they didn't involve a formal ceremony or any witnesses. However, they were considered legal and binding, so the couple could live together as husband and wife without fear of legal repercussions.
Today, knobstick weddings are not very common, as there are many other affordable and more convenient ways to get married. However, they are still considered an interesting part of history that helps us remember how people used to live and get married in the past.
