Slattern
noun
1. An untidy, dirty woman.
2. A prostitute who attracts customers by walking the streets [syn:
streetwalker]
1639, "a rude, ill-bred woman," probably related to Low Ger. Slattje, Du. slodder, dialectal Sw. slata "slut" (in the older, non-sexual sense). Cf. dial. Eng. verb slatter "to spill or splash awkwardly, to waste," used of women or girls considered untidy or slovenly.
