I think it's the housing for one of the atom bombs dropped over Hiroshima & Nagasaki - little boy for fat man.

In South Africa, adolescent Xhosa boys are circumcised and then get sent into the wilderness to live off the land for a few weeks.

The problem is, circumcisions are performed by traditional leaders in the most unsanitary conditions with unsterilised knives. The result is that every year several boys die from infections or associated complications...

At least there is a government-backed initiative to formalise (sterilise) the ceremony.
