The Ghost looks like a creature begotten by the Maharishi Mahesh Yogi on a Tibetan mountain goat: it comes in crawling on its belly surrounded by dry ice, then rises and lunges into caprine capers.
-- John Simon, "Spamlet," New York, 1969
Goats are more curious than horses and ponies, so until they're fully seasoned, allow them to carefully examine equipment each time you expect them to wear it. Take caprine nature into consideration when training a goat to drive.
-- Maggie Sayer, Storey's Guide to Raising Meat Goats, 2007
Caprine is derived from the Latin word for "goat," caper. It entered English in the early 1600s.
