Word Origin for hackle
Old English hacele "cloak, mantle" (cf. Old High German hachul, Gothic hakuls "cloak;" Old Norse hekla "hooded frock"). Sense of "bird plumage" is first recorded early 15c., though this might be from unrelated Middle English hackle "flax comb" (see heckle (n.)) on supposed resemblance of comb to ruffled feathers. Metaphoric extension found in raise one's hackles (as a cock does when angry) is first recorded 1881.
raise one's hackles
Make one very angry, as in That really raised my hackles when he pitched straight at the batter's head. Hackles are the hairs on the back of an animal's neck, which stick up when the animal feels fearful or angry. [Late 1800s]
