What does crabbier mean?
"Crabbier" is the comparative form of "crabby," an informal adjective describing someone who is irritable, grouchy, or easily annoyed. When a person is described as crabbier, it means they are displaying more bad temper than before, or more than someone else — for example, after a sleepless night or during a stressful week. The word carries a mildly humorous, colloquial tone rather than a clinical one: it suggests everyday grumpiness rather than serious anger or depression. It derives ultimately from "crab," the crustacean, whose sideways walk and tendency to pinch inspired the figurative sense of a prickly, disagreeable personality. Related forms include "crabbily" and "crabbiest." Because it is informal, "crabbier" suits casual speech and light writing better than formal or academic contexts, where terms like "irritable" or "irascible" would be preferred.

Etymology of crabbier
The adjective "crabby" (and hence its comparative "crabbier") derives from "crab," the name of the crustacean, which entered Middle English from Old English "crabb(a)" and shares Germanic roots with related words in Dutch and German. By the early modern period, English speakers were using "crab" figuratively for a sour-tempered or contrary person — likely influenced both by the animal's backward, awkward movement and by "crabbed," an older adjective meaning difficult or ill-natured. The extended sense of "crabby" meaning irritable became common in American English by the 19th century.
