Pilgarlic or Pilld Garlic (A).
One whose hair has fallen off from dissipation. Stow says of one getting bald: He will soon be a peeled garlic like myself. Generally a poor wretch avoided and forsaken by his fellows. The editor of Notes and Queries says that garlic was a prime specific for leprosy, so that garlic and leprosy became inseparably associated. As lepers had to pill their own garlie, they were nicknamed Pil-garlics, and anyone shunned like a leper was so called like-wise. (To pill = to peel; see Gen. xxx. 37.)
It must be borne in mind that at one time garlic was much more commonly used in England than it is now.
After this [feast] we jogged off to bed for the night; but never a bit could poor pilgarlic sleep one wink, for the everlasting jingle of bells.Rabelais: Pantagruel, v. 7.
