Hey Keith, i'm used to being a minority mate. The only time we would use that expression in my mob would be implied with a derogatory reference to the effeminate practice of dabbing ones toe in the water (a nasty habit of RN snotties btw ) to test the water temperature before jumping, falling, or being blown in to the oggin; therefore earning it the inflection of being a Queer. However i'm sure Cyril (et al) used it to refer to New Entries OD's JOS's and below, but I studied at the North Atlantic University of Couth and Culture in a much harsher marine environment, where such references would usually end up with a boot in the nadgers, just in case it was used as a derogatory inflection meaning queer.
Guess we were wrong ;-)
Cheers, Yours Aye Dave ;-)
