stummock

   Also ‘slammock’, which appears to have been the original form of the word in English dialect. A slummock is a slut, and the term is ‘frequently used as a disrespectful term of address’, according to the Supplement to the Oxford English Dictionary, though it quotes no vocative examples. Up the City Road, by John Stroud, has a man saying to a young woman: ‘you bloody horrible little slummock’. ‘Will you mind your language, please?’ she replies.
