Physical Tourettes
A diagnosis usually made by friends for someone who displays many over-exaggerated, animated movements people use to tell a story or describe something. These are usually short bursts of movement that seem uncontrolled or in most cases just not thought about before being executed. Most people know at least one person who displays signs of Physical Tourettes. Occurrences usually happen more often when alcohol is involved.
Trying to pick people out in a crowd with physical tourettes makes for light drinking entertainment!
