one's own legs, especially as a means of moving from one place to another. From the phrase to go by Shank's mare (or pony): get somewhere on one's own feet, to walk. The origin is not known, but it has been stated that it refers to King Edward I (1239 - 1307), nicknamed "Long Shanks," because whenever he rode a pony his long legs reached to the ground. "Shank" is the part of the leg between the knee and the ankle. —PDC 2 Approved Glossary
