shellac

v. coat with varnish; rout, defeat soundly (Slang)

n. lac that has been purified and processed into thin sheets or flakes; varnish made from processed lac dissolved in alcohol (also shellack)

Shellac is a brittle or flaky secretion of the lac insect Kerria lacca, found in the forests of Assam and Thailand. Freed from wood it is called "seedlac".Once it was commonly believed that shellac was a resin obtained from the wings of an insect (order Hemiptera) found in India. In actuality, shellac is obtained from the secretion of the female insect, harvested from the bark of the trees where she deposits it to provide a sticky hold on the trunk. There is a risk that the harvesting process can scoop the insect up along with the secretion, leading to its death. The natural coloration of lac residue is greatly influenced by the sap consumed by the lac insect and the season of the harvest. Generally in the trade of seedlac there are two distinct colors; the orange Bysacki and the blonde Kushmi.
