There’s a phrase I enjoy (in modified form) to describe when my middle daughter employs her black arts to irritate me in some simple, but effective way: “She has my goat in her pocket.”
The classic saying, “to get your goat,” basically means: to irritate; annoy; make someone feel bad; a successful tease.
According to several sources, including idiom.com and The Phrase Finder, its idiomatic debut stems from a story reporting on a burst water pipe in The Stevens Point Daily Journal, a newspaper in Wisconsin, from May 1909:
“Wouldn’t that get your goat? We’d been transferring the same water all night from the tub to the bowl and back again.”
Its export across the pond is listed in 1924, found within the story, “The White Monkey,” by English author John Galsworthy: “That had got the chairman’s goat! – Got his goat? What expressions they utilized these days!”
