The traditional ceremony is called "Igbankwu," or wine carrying, because it involves the bride carrying a cup of wine to her groom.
The bride's father fills a cup (Iko) with palm wine and passes it on to the girl while the groom finds a place between the guests.
It is the custom for her to look for her husband while being distracted by the invitees. Only after she has found the groom, offered the cup to him and he has sipped the wine, is the couple married traditionally.
During this ceremony, there is also the nuptial dance where the couple dances, while guests wish the newly weds prosperity by throwing money around them or putting bills on their forehead.
