I'm not sure what's tired about saying that you shouldn't misappropriate words instead of choosing available ones but I'll yawn if it makes you happier.
On non-profits, whether a show extends or transfers misses the point. Shows are budgeted (expenses, ticket revenue, and contributed funds if you are lucky) and need to hit certain targets. Non-profits still have to cover costs or suffer the consequences. Whether you call it a flop or a dud or something else, the "idea" of a non-profit is not to lose money.
I'm happy to discuss this with you more, in a non-snarky way, if you want to flesh this subject out any more.
