I've been looking for some information regarding traditional Macedonian weddings, I've a few things but the details below seems to be the clearest one to understant. From what I can gather, as a best man, I don't have to do much except, throw coins in the path of the newly wed. I'm sure I can manage that.
The coin below is a Macedonian Denar. At the current exchange rate you can get 36 of these for 1 Australian Dollar.
On the wedding day the bride is taken from her home by the "bride's guard", accompanied by a band or orchestra. They drink a toast to the bride and groom and the couple are allowed to see each other briefly, as the toast is drunk.
They all leave for the church and the band plays a traditional song on the way. In the church the wedding party marches to the altar, accompanied by choir music, and there they go through a brief betrothal ceremony in which the bride and groom are given their rings. The wedding party then marshes to the center of the church, where there is a table bearing the Bible, a cross, a cup or wine and two crowns. The priest gives the instructive sermon, asking the participants specific questions pertaining to their free wills. Then, the priest ties the right hands or the participants together, symbolizing the one-ness or the marriage.
Next, the crowns are placed on their heads, representing the coronation of glory with which the husband and wife hope to be blessed with in their future lives. After this, the formula of the wedding is pronounced as the priest says, three times, "Oh Lord, our God, crown them with glory and honor." There is then a reading or the gospel and the bride and groom are given the cup of blessed wine symbolizing the mutual life in which they will accept the good with the bad, the bitter with the sweet, together in blessed love and understanding. Finally, the wedding party, preceded by the priest, walks three times around the table, signifying the eternal path of marriage.
The newlyweds are congratulated by friends and, on the way out or the church, the best man (kum) throws coins in the couple's path, to wish them good luck and prosperity. Then, the wedding party goes to the bride's home, or some other suitable place to celebrate. There the guests dance the oro, toast the bride and groom, and (instead of presents) give money to the honored couple. This is done to give the couple good start (financially) on their new life. Later on the bride is taken to the home or the groom to meet the small children, whom she kisses three times. This symbolizes the bride's desire for children of her own. The bride's mother-in-law' gives her wine and bread to symbolize the wish for harmony and happiness between them.
