Origin: 1665–75; cf. dial. fidge to fidget, akin to the synonymous expressive words fitch, fig, fike; cf. ON fīkjast to be eager, OSw fīkja to be restless
1674, as the fidget "uneasiness," later the fidgets, from a 16c. v. fidge "move restlessly," from M.E. fiken "to fidget, hasten," from O.N. fikjask "to desire eagerly" (cf. Ger. ficken "to move about briskly;" see fuck). The v. fidget is first attested 1672 (implied in fidgetting).
