Rather than Troll, which though coopted by the fantasy context probably began as a fishing reference, how about these monklike terms that might apply to someone who lazily expects a free handout:

acedian: Perhaps cryptic, but generally refers to someone remiss in their practice of virtue; i.e., someone guilty of sloth.

mendicant: Someone dependent on begging for their survival. Though this could be construed in a more benign way, such as a practicing member of the Franciscan order, it does indeed have a prior meaning that might encompass the meaning we seek.

I´m sure there are plenty more ideas out there. Anyone?
