Twistaflexing 

The over exaggeration of every movement of the body from someone high on methamphetamines. The user will twist and flex and bend their body in unusual and unnatural ways with every body movement. This typically happens when the user has been awake with no sleep for way to long. Methamphetamines does not effect every person that uses in this way.

Look at the way that tweaker is walking, he's a twistaflexing professional.
