look up any word, like blumpkin:
 
1.
A ritual performed by amazonian tribesmen wherein the males take turns "having their way" with a captured foreigner in exchange for their lives.

Usually the foreigner will be given the choice of "Mugundo or death", though death BY Mugundo has also been implemented in the past.
Guy 1: Do you know what happened to Erik and Zach?
Guy 2: Yeah man, they got freakin' mugundo'd.
Guy 1: No way!
Guy 2: Yeah, it was pretty sick. They still can't sit down.
