Lest I be "speared", I have no wish to disrespect Huorini / Waodoni culture.
The Huaorani believe that when someone dies, the soul starts a journey towards heaven. On the way, in the middle of the path, a big anaconda is obstructing the way. Only brave souls can jump the boa and reach heaven. Whoever fails, returns to earth as a termite, and leads a miserable existence.However, if your first exposure to the term is the discussion in a pretty, but clumsily made movie (The End of the Spear), glorifying missionary work, over when particular characters "jumped the great boa"... similar expressions come to mind. I thus propose "Jumped the Boa" as a term to describe when Christian-themed entertainment goes way off mark.
