whickerbill n. 1. (the foreskin of) a penis; 2. an unsophisticated person or rustic; 3. a thin, raised edge on a airfoil or fan blade that adds downward force. Also wicker bill, whickerbill, wickerbill. Editorial Note: Similar synonyms for the first two senses are peckerhead and peckerwood, both in a literal definition ‘(a part of) a penis’ and in a more derogatory one, ‘an unsophisticated person; a redneck.’ Another synonym for the second sense is scissorbill.
