fike (v.) Look up fike at Dictionary.com
Middle English fyken "move about restlessly" (early 13c.), from Old Norse fikjask "to desire eagerly," fika (in fika sig upp "climb up nimbly," of a spider), probably from a general North Sea Germanic word related to the source of German ficken "to move about briskly." Later as "give trouble, vex" (1570s), a sense surviving especially in Scottish. Hence also fikery "vexatious trouble" (1823); fiky "causing trouble about trifles" (1768).
