Abeyant (a) - Temporarily do nothing through a deliberate suspension. Generally a legal term for delaying an action.
Indolent (a) - Being a lazy do-nothing, lacking the will to do something.
Quiescent (a) - To do nothing by being in a state of rest or sleep.

Zugzwang (n) - German for "compulsion to move." In chess it is used to describe a situation where doing nothing is better than doing anything. Since, in chess, declaring pass is not an option, Zugzwang is a bad place to be.
