Why was "tantrum" trending last week?
1630s, "a woman negligent or disordered in her dress or household," of uncertain origin, probably related to Low German Slattje, Dutch slodder, dialectal Swedish slata "slut" (in the older, non-sexual sense; cf. slut). Cf. dialectal English verb slatter "to spill or splash awkwardly, to waste," used of women or girls considered untidy or slovenly.
