What's the sign for "God help us all"?

We made the mistake of giving M- the gift of communication, in the form of the baby-sign-language sign for "more", which is made by touching all your fingers together, as pictured above.

Her version usually approximates this, but at its worst it degenerates into her pointing at her palm demandingly, as seen below:
She also has expanded this beyond mealtime, to mean "gimme that toy", "pick me up now", and generally, "give me exactly what I want immediately."

Now we just need to teach her to understand my sign for "I see and understand what you are communicating, but I must deny you what you want for unspecified reasons."

I think I may need more fingers.
