A mental meltdown of epic proportions. Usually associated with otherwise extremely successful business managers/owners. Characterized by blaming others for self-inflicted pain caused by poor planning.
A manager shows up to work in the morning to find all his employees have quit and has to calm a pissed off client. Later that day finds he has no plan to fix his problems, and proceeds to blame the distict manager for his problems while assuming the fetal position and murmuring for his mother. This individual would be said to have experienced A Shaffer Meltdown.
