A neurotic condition whereby a self-important person has the need to answer a cell phone call or continue a cell phone conversation regardless of the awkwardness of the situation or location where the call is taking place.
Airport restrooms are great locations for observing cell whores and this odd behavior.
Skip is such a cell whore, he took a call from his office, walked to the men's room, did his "business", flushed, and walked back to his office. All this and he never missed a beat. He kept the conversation going, except he did not wash his hands.
