c.1369, probably from O.N. *krasa "shatter," perhaps via an O.Fr. form. Originally "to shatter;" now-obsolete metaphoric use for "break down in health" (1476) led to n. sense of "mental breakdown." Extension to "mania, fad," is first recorded 1813. Original sense preserved in crazy quilt pattern. Crazy is from 1576 as "sickly;" from 1617 as "insane;" and from 1927 in jazz slang for "cool, exciting." Phrase crazy like a fox recorded from 1935.
