mallemaroking

Generally considered to derive from Dutch, although a specific etymon is unclear. Century and some other old dictionaries derive it from a confusion of two similar Dutch words, namely *mallemerok (“foolish woman”) (from malle (“foolish”) + *marok, from French marotte (“jester's sceptre”)) and *mallemok (“sailor of a whaling vessel”), but the first of those words is not attested, and the second is not attested with the claimed meaning (but see mollymawk). Compare mallemolen.
