crumpet (n.)

sort of tea-cake, 1690s, perhaps from crompid cake "wafer," literally "curled-up cake" (1382; Wyclif's rendering of Hebrew raqiq in Exodus xxix.23), from crompid, past participle of crumpen "curl up" (see crumple (v.)). Alternative etymology is from Celtic (compare Breton krampoez "thin, flat cake"). Slang meaning "woman regarded as a sex object" is first recorded 1936.
