Thank you for clearing that up Kieth and apologies. I had missed that.

And 999, fair point, but the dictionary makes no mention of male sluts in it's definition either and there was no assumption being made... I have only ever heard it used perjoratively against women

slut [slVt] noun
    1             a dirty slatternly woman

    2             an immoral woman

    3 (Archaic)             a female dog

            [C14: of unknown origin]
        *sluttish adjective
        *sluttishly adverb
        *sluttishness noun

Personally I have never heard slut used against a man except in some way some would call humour and it usually refers to their rakishness or cad like behaviour. I could well be wrong. The urban dictionary uses several definitions.
