passolapse
noun
A feeling of sitting inertly as time stretches on, accompanied by a lack of motivation or interest in any activity. Your mind is blank, helplessly aware of time's relentless passage as you search for something to spark your spirit.
From Latin 'passus' (step or pace) + Latin 'lapse' (slip or slide), representing the slipping away of time as one remains immobile. Pronounced "PAS-oh-laps"
