What (who) is Skitterback - definition

To make a clicking noise in the same way one taps a can of chewing tobacco, by holding the middle finger and thumb together, and flicking the wrist, to make the index finger collide with the other two fingers to produce a snapping noise.
The practice originates in (don't laugh) Morehead, Kentucky, where two students invented it in order to annoy a teacher (let's get her back). It is now used also to honor things that one deems cool.
