There's the old story of the 3 missionaries who are caught by the tribesmen and they have to choose between Death and Tonga.
The first two choose Tonga to the delight of the tribe who start chanting "Tonga Tonga Tonga" before commmitting the unthinkable on the unlucky missionaries.
Finally, having witnessed the proceedings the third missionary bravely chooses Death at which point the chief announces...
"Very well - I sentence you to Death......by Tonga".
Some folks tell this story and use the word "bofumba" instead of "Tonga".
