A Darrenator is a person who occupys an entry-level technical position, such as help desk, who wrongly believes he possesses as much (or more) technical knowledge than senior members of the department. The typical Darrenator will take every opportunity to display his complete lack of knowledge in the mistaken belief that this will somehow impress, if not intimidate, those around him.
In certain respects, the Darrenator exhibits behavior consistent with the common "ultratard" but is simultaneously more highly motivated to win the esteem of his co-workers and almost totally ignorant of the level of his own ignorance.
