There is a popular game that boys of my generation enjoyed playing. It was simply called the game of throwing urine. I am told it is still very popular among male children in different Kenyan communities. It involved lining up in a straight line while facing one direction and each one of us would hold his 'gun' in his hands to throw urine. The one who threw his urine the furthest won the contest.
Like any other male game, it defined our masculinity. The winner was obviously the boy who threw his urine furthest. If say your performance was abysmal, then you were looked at as effeminate and you immediately lost your identity among "we men". To play this game successfully we would first take lots of water in preparation.
