Have you suffered from Headquartersitis? Do you have it, or know someone who does?

Someone recently asked for my definition. Here it is:

Headquartersitis is a disease that may be unique to Washington DC. The virus-like illness tends to exist in clusters. It is believed to spread from person to person by breathing lofty air in offices and subways. The illness is first presented by a smug appearance and an air of pseudo-authority. Symptoms randomly manifest via repetitive streams of self-fulfilling prophesies, paternalistic approaches, and reckless disregard for the welfare of less fortunate workers in the field who tend to be naturally immune. Clusters are identified by cliques who tend to reward one another. Left untreated, the disease reaches a critical point marked by delusions. Diagnosis can be confirmed by a patient’s steadfast belief that people who work in the beltway are elite Savants. Such delusions often spiral into a thick morass of uncontrolled feelings of self-importance, criminal acts, and epidemics of extremely low morale centered around the patient. Treatments are few. They include repeated exposures to media headlines, banishment, incarcerations, resignations, or retirement. The first recorded case of H-disease was in 400 BC, among politicians during the sack of Rome.
