Jossed = Joss Whedon? [Buffy on the brain as always]

Oh, yes. "To get Jossed" is when you spend oodles of time laboring on your fanfic -- only to have Minions of Satan the producers come out with an episode showing your fanfic's basis is Wrong Wrong Wrong. A common occurrence for anyone crazed enough to attempt speculative fanfic based on a Joss Whedon show. ;_;
