To describe each individual jiggle is impossible. It is rare that a jiggle-pattern is ever repeated. However, the basic classes of jiggle can be defined, as well as sub-classes, or modifiers. Classes and modifiers combine to create a single, unique jiggle-pattern.
First, subclasses will be explained.
syncronous: In two-leg jiggle-patterns, having identical jiggles--left up, right up. Left down, right down.
Antisyncronous: left up, right down, right down, left up. A difficult subclass.
Use: Energy release. Aggravation.
speed: rapidity of jiggle.
Use: Energy Release. Rythym. Aggravation.
Alternate: In two-leg patterns, a jiggle that switches left and right roles every cycle. For instance. Left left right. right right left. (with the single pattern left left right)
Overlapping: an alternate jiggle-pattern that overlaps: left left right right left left right right, (with the single pattern left left right)
On-off: a jiggle pattern with a blank space btw each/every _ repititions. (rightrightright..........rightrightright)
Use: Focus. Rythym.
Full alternate: Alternate in which the entire repitition is jiggled first by one foot, then the other (left...leftleftleft right....rightrightright)
Not all subclasses can modify all classes. Obviously, a single foot class of jiggle cannot alternate. They can be applied to any "basic" class, similar to translation, stretching, and flipping on a graph.
Most jiggle patterns can be changed from the basic use to another, by modification through subclasses. Remember, all jiggles can produce energy release, focus, rythym, or aggravation; the uses listed are just those most improved by the addition of the subclass.
Before I go any further I must condemn the use of foot-jiggling as an aggravant. Otherwise I might be held accountable when everyone becomes just that much more annoying due to modifying their jiggle for aggravation. It is not nice to aggravate people. If someone asks you to stop jiggling, do your very best to do so. Remember how you feel when things drive you crazy. And consider others better than yourself.
