When you cut a hole in the side of a box and have your partner lay her head in it, then have all your friends gather around and shit in it until the box is filled and you can no longer see your partner's face.

An annual tradition when a 16 year old male turns 16. The family blows up balloons and the male ejaculates in each uninflated balloon, and then had a countdown to when the male would turn 16, and at that moment they would fill up the balloons and pop them, showering everyone in the male's semen. Then, the mother of the family has a "special" time with the male in a private dormitory as in "initiation" into manhood.
