stiffy

To do this trick get some air off a jump and do an indy. Next bring your legs up so they are (roughly) parallel with the ground. Fully extend your legs as if stretching. This requires some stretching/gymnastic ability. When you are going to land bend your knees and return to your normal stance.

(b) In wakeboarding, a technique of intermediate difficulty where the rider extends his/her legs after the board passes over the crest of a wake, bringing the board forward.

(c) In South Africa, a stiffy is a slang word for a 3½ inch floppy disk.

Non-South Africans can get some wry amusement in reading South African technical manuals or discussion fora, viz:

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.
