So, I guess I will try to describe Kumbati (somebody please tell me how to spell this!).
Once you play it, it will become obvious what it is training you for.
This is meant to be played outside.
There are two roughly equal teams, one on each side of a line on the ground.
The goal of the game is to get everybody onto your side of the line, using whatever tactics are necessary.
For example, if there is a strong player on the other side, you and a teammate can make a plan to run across the line, one of you taking his legs and taking him down, then both of you carrying him across the line back to your side.
The catch is, however, that while on the other side of the line, you must constantly be shouting "kumbati kumbati kumbati" and if you run out of breath, or are held on that side until you stop saying it, you now join that team.
It gets really chaotic when you are defending against snatch squads while simutaniously planning ways to grab opposing players.
It is super fun, super physical, and everybody is on the winning team in the end (unless you designate one side of the line the cop side).
What do you call this game?
