• It's actually "had a wild hare", as in a rabbit. It's an American expression meaning to do something at the spur of the moment without really thinking, spontaneity. It originated from "had a wild hare up my <insert rated "G" synonym>". If you had a wild rabbit in your backside... you'd probably jump without thinking. It most likely originated in the Mid-West where hare were commoner'n a fly on a horses' .. (and so was vulgar language). But as it was shaved down, it can now be used as "I had a wild hare to go to Vegas".
