Dang, I'm not sure if that book title should be underlined. I suck at MLA formatting.
Pokładziny-The Bedding Down
In ancient times, putting the bridal pair to bed was a normal and expected part of the marriage customs, and was down with much joking and hilarity. The young couple were directed by the entire wedding party to a room that had been specially prepared for them. The swat, still overseeing that all went according to custom, placed himself on the marriage bed to "warm it up". The womenfolk jumped up and down on the bed to make sure it could hold up and now break down. Rocks or sharp straw or thorns might have been placed underneath the sheets. The swat and swata then chased everyone out of the room and took the bride and groom to the bed and left them alone. The door was locked behind them and after serenading the bridal couple with some very warm and bawdy songs, along with vodka toasts and admonitions "not to be lazy," the couple were left alone.
The next morning, musicians awake the couple and gave them kasza cooked in milk and vodka that had been dyed red as a sign of lost virginity. The sheets were inspected for the expected stain that meant the loss of virginity. This made everybody happy and was the cause of more singing and dancing.
From "Polish Customs, Traditions and Folklore" by Sophie Hodorowicz Knab
Just so you know, we won't need any warnings against being lazy, and there will be no singing and dancing at the loss of my virginity, unless it is by yours truly.
