1920-25; < French, masculine derivative of gigolette woman of the streets or public dance halls, probably ultimately derivative of Middle Frenchgiguer to frolic (see jig2); cf. giglet, Middle Englishgig(e)lot, which may have influenced gigolette
1922, from Fr. gigolo, formed as a masc. of gigole "tall, thin woman; dancing girl; prostitute," perhaps from verb gigoter "to move the shanks, hop," from gigue "shank," also "fiddle," of Gmc. origin. This is perhaps the same word that was borrowed earlier as M.E. giglot (mid-14c.) "lewd, wanton girl," which was later applied to males (1520s) with the sense "villainous man." M.E. gigletry meant "lasciviousness" (late 14c.).
