"Hitch in your git-along"..type of phrase

Posted by Patty on August 22, 2001

My great granny used to use phrases like "he's got a hitch in his git-along" (meaning: he's momentarily thwarted, or he's no self-starter). Is there a categorical term for this type of folk phrase? Is there a book that has collected these from old rural America? Thanks.......
