Technically "Guyettes" is more of a "Gennessean" phrase, being the sort of term that one comes up with while considering a keg of Gennessee that has already been tipped on its side to get the rest of it out...
This falls very much in line with the "Fosterite" term "Shiela's" which is prevalent in the vicinity of Perth, Freemantle, Sydney, and the more trendy areas of Los Angeles County.
Far more disturbing is the language found in the growing population of "Natural Iced" citizens, who seem to have some difficulty destinguishing between practitioners of the oldest profession and holes in the ground.
