Three men are stranded on an island and a tribe appears from no where.

The chief says to them, Ungubunga or death.

The first guy asks the chief, What is ungubunga? and the chief simply repeats himself.

The first guy says,Ungubunga and the chief screws him and lets him go.

The second guy says, Well its pretty disgusting, but I have a family. so he chooses ungubunga and gets screwed.

The third guy says, You two are disgusting! and chooses death. the chief exclaims, Good choice death by ungubunga!
