What does swayback mean?
A swayback is a distinctly arched, rounded, or outwardly curved back. The term is used most often in descriptions of horses and cattle, especially older animals whose spines and supporting muscles may become increasingly curved. It can name the physical condition itself, as in "a horse with a pronounced swayback," or function as an adjective describing an animal or object with that shape. Applied informally to a person sitting or reclining, it usually suggests an exaggerated backward lean and may carry a humorous, mildly mocking tone. Swayback is related in meaning to arched back and rounded back, though it often implies a more conspicuous degree of curvature. The word is especially useful in equestrian, veterinary, agricultural, and livestock contexts, while its figurative and humorous use allows it to characterize an unusually relaxed or reclining posture.
An arched or convex curve in the back, especially of a horse or other animal; also a person or animal with such a curved back.
"The veterinarian examined the pronounced swayback of the aging mare."
Common in descriptions of livestock and horses; when used of a person's posture, it is often informal and humorous.
Having an arched, rounded, or outwardly curved back.
"A swayback horse stood quietly beside the fence."
The related form "swaybacked" is especially common when describing an animal.
Used mainly when referring to individual animals or people with a characteristic arched back.
"Several swaybacks grazed beside the boundary fence."
A swayback can look dramatic, but in horses it often develops gradually with age as the spine and supporting muscles weaken.

Etymology of swayback
Swayback is a compound formed in the early 19th century from "sway" and "back." Its early agricultural use referred to the arched back of a horse or cow, with "sway" conveying a bend, lean, or curve. The word later developed broader uses for rounded or reclining backs and is still most strongly associated with animal conformation.
