To anticipate something with obvious pleasure. The word chops (or chaps) has meant the jaws or mouth since about 1350, usually referring to the lower jaw of animals.

In jazz slang of the 1930s and 1940s, licking one’s chops meant warming up before a performance. In jazz parlance chops also came to mean ability or skill, a usage from the 1960s.
