A friend has lent me several Harlan Coben books (pretty good but not great, imho), and in some of them, characters are referred to as having or "sporting" a soul patch. For all I knew it was some kind of tattoo.
Today I finally tried looking it up online, to find that it is a kind of, well, patch, of facial hair. But I found different "definitions"; one place said that basically it was a goatee; another, that it was a small tuft just beneath the lower lip and above the chin.
Is there anybody more in touch with the real world than I am who can tell me for sure what it is?
