8. Bathroom Ban of Tidong Weddings in the Indonesian Tidong community have traditions that are truly unique. Perhaps the most adorable of their customs is the one where the groom isn't allowed to see the bride's face until he sings her several love songs. But the weirdest of them all is this – the bride and the groom aren't allowed to use the bathroom for three days and nights after the wedding. Tidong people believe that not practicing the three-day and night ritual would bring terrible luck to the couple.
