burn the money

The act of revealing the ending to a movie and/or event (especially something that relies upon the ending to create suspense & drama), thereby making it unwatchable.

(Derived from the movie A Simple Plan - and, if you haven't seen it, well, I just burned the money)

Jackass: "Man, if I was A Simple Plan, I wouldn't burn the money, those idiots."
Foil: "Wait...they burn the money at the end? Thanks Jackass, way to burn the money."
