Obs. [A perversion of chichefache, north. Fr. form of chicheface, chincheface lit. thin-face, niggard-face, ugly face, une chimère dont ils font peur aux petits enfants (see Godefroy). The perverted chichevache = ugly or lean cow, is found only in Eng., and, so far as is known, first in Chaucer. (See Montaiglon, Poésie franç. 15e et 16e siècles (1855), II. 191.)] The proper name of a fabulous monster said to feed only on patient wives, and hence, from the scarcity of the diet, to be always lean and hungry. Cf. BYCORNE.
