threading
Threading is a often a footwork tech done by bboys and bbgirls in the dance of bboying.  It creates an illusion as if some part of the body is being continually threaded.

There are many variations to threading.  First, threading can be done in toprock, footwork, and freezes.  Second, threading can be done with any body part and even clothes, creating the effect of twisting and bending the body into abnormal positions, or to revert back into the starting position.

Threading in footwork is often used as a transition move in order to get into another move.  Threading is also common in freezes, often combined with airchairs and handstands.
Lilou, a famous French BBoy, is known for his skills in threading.
