Johni Kibogoyo

There was no better way to silence an opponent in a competitive game (or to wind up an argument you were clearly losing) than to whip out Johni Kibogoyo. The only modification needed was to substitute 'Johni' with the other kids name.

Johni Kibogogyo, alihara kwa mkebe
Akasema ni wageni
Wageni wakasema
Ni Johni Kibogoyo!

I imagine that it created such vivid imagery in the victim's mind that they just couldn't help seeing themselves doing something nasty in a tin. Worked every time!
