Tedious means so long and dull it wears your patience away. A tedious meeting, tedious work, tediously slow.
The length is essential — a boring moment is not tedious, and a tedious task is dull and keeps going. It is a complaint about the effect on you rather than about the thing. The Latin taedium means weariness.
