A leadership position obtained by force or marked by flagrant asshole behavior and blatant disregard for facts, advice, or common courtesy. An assholership is a dictator-like position where all reasoning is attributed to "my way or the highway" or "because I said so".
This new boss just ignored everything I had to say about the new project - he's running a total assholership up there.
