At Puget Sound Guitar Workshop they called it Complicated Chord Disorder (or was it Syndrome?) At any rate it is supposed to occur at a certain stage of your guitar playing development when you have discovered the more outre chords and ways of playing, and can't let go of anything you learned up to that point.
It can lead to some really tedious, if showy, arrangements of standards.

They also coined the acronym "FOMS" for another thing that happens to people there. It occurs when multiple workshops and events are scheduled at the same time and stands for Fear Of Missing Something.
