Drinking a genuine alcoholic beverage

The women were singing loudly and playing a little trumpet calling other Hamer people settled on the valley. In other side the men chating excitedly and in the midle a genuine alcoholic beverage which everyone drinks in great amount.... even little children. The neighbors come playing theirs trumpets and entered in the village crossing a simbolic gate built with dry branches.The women started to dance and suddenly appear in the dancing floor some men with whips in their hands . The women,relatives of the protagonist, in order to enhance the confidence on him, offering their backs to be whipped.(I couldn´t shot any pic at these moments , my fingers were paralyzed).To minimize the hurt they started a frenetic dance for a long time. Once finished the dance, they were to proudly show their bleeding backs to their husbands .The party continued till sunset when the young men make a row with many of the cattle of the tribe. The protagonist, completely naked, must jump and walk over the back of them many times till the elder of the tribe decide he has passed the exam then everybody sing and jump.........expressing any kind of joy
