A bambulu is based upon an ancient ritual from tribes in eastern Kenya in Africa where where young male warriors, in order to be accepted into adulthood, had to spend 10 minutes in a hut with every other adult male warrior of the tribe.

Timmy 1 - It's best to avoid a bambulu session.
Timmy 2 - What's that?
Timmy 1 - It's a right of passage in eastern kenya where you get dominated.
Timmy 2 - That sounds painful in the anal.
