means To exceed a set limit of time, budget, or space — or to spread over and occupy a place in greater numbers than wanted.

from A straightforward compound of 'over' (beyond, in excess) and 'run' (to proceed, extend, operate), both ordinary Old English words. It first described armies or vermin running past boundaries and flooding a territory, then stretched naturally to cover meetings, budgets, and schedules doing the same thing — spilling past the edge they were supposed to respect.
