Mary Poppins Syndrome 

A psychological disturbance, usually starting in childhood, wherein a person eats teaspoons of sugar back to back, practices telekinesis in order to clean up their room and periodically jumps off rooftops holding an open black umbrella.

It first became apparent to me at about the age of 12, as my parents were divorcing, that I was suffering with a deeply rooted and seriously advanced case of Mary Poppins Syndrome!
