Somewhat morose, gloomy, or bad-tempered; having a sullen or sour disposition.
Possibly related to or derived from 'glum' (morose) + '-ish' (somewhat). The word appears in dialectal English, particularly Scottish, from at least the 1700s, though its exact origin is uncertain.
This Scottish word perfectly captures that grumpy morning mood before coffee—it's more serious than just being grumpy, suggesting a deeper, settled sourness of mood.
