Sullen, Sulky. Both sullen and sulky show themselves in the demeanor. Sullenness seems to be an habitual sulkiness, and sulkiness a temporary sullenness. The former may be an innate disposition; the latter, a disposition occasioned by recent injury. Thus we are in a sullen mood, and in a sulky fit. No cheerful breeze this sullen region knows; The dreaded east is all the wind that blows. (pope)
