stiffy n.
3.5-inch microfloppies, so called because their jackets are more rigid than those of the 5.25-inch and the (now totally obsolete) 8-inch floppy. Elsewhere this might be called a `firmy'. For some odd reason, several sources have taken the trouble to inform us that this term is widespread in South Africa. Australians, on the other hand, suggest being careful with it when Down Under, as it is there universally slang for an erection.
