The term Biruva has been derived from Billava. Bila means break or defeating therefore, the name indicates the community of strong men. Billavas are variants of Villavars also known as archers and therefore are best known as warrior caste of the Dravidians who have ruled ancient India. The martial art academies of Billavas are known as Garadi. Garadi's major activities are reading, writing, archery and martial arts. Billavas are considered as descendants of these ancient Villavar warriors. Tulu is the main language spoken by Billavas and in some areas of Karnataka, Billavas also speak Kannada therefore people also recognize them as "Kannada Billavas". Billavas grooms and brides can be found with surnames like Amin, Baidya, Baishya, Banan, Gujran, Kotian, Palan, Sanil, Suvarana, Talwar and many others.

Few women relatives of the girl go to the water pool, tank, well or pond and brings water in earthen pots and the girl bathes from that water. On the wedding day the Billavas groom and bride are made seated on two planks. Then the barber arranges rice, flowers, lights, betel leaves and other essential items with vessel full of water, all of which is required for rites and rituals of ceremonial tradition. The barber then joins the hands of couple, their parents, places the node pin of the bride on their hands and pours holy water over them.
