doldrum

A slothful or stupid person.

Were there no "tears and miseries," when the half-witted doldrums, thinking they were not big enough to be seen, put themselves on horseback, to bask and frolic in a procession, and meet their man-midwife, or surgeon, or whatever he is, who had left his business at Norwich, to go to London, for the purpose of administering their little nostrum to the Prince Regent?

Boring, uninteresting.

She quit her doldrum job and left to seek a life of adventure.
