I've used "Aiya Earendil Elenion Ancalime" before. Usually it accompanies a banging of a flashlight on a tree or some other appropriate surface.

Another one I use is "Get thee gone and take thy due place" to get people to leave me alone. It usually works, most likely because of the middle-late english pronouns.

Ah, middle-late english pronouns. Those little buggers have gotten me out of some pretty tight spaces.
