ditto monkey

A person who vapidly, unthinkingly yet wholeheartedly repeats, shares and takes to heart phrases and ideas he/she hears from his perceived leader. Most often (OK, damned near exclusively) applied to followers of right-wing media magnates like Rush Limbaugh, Michael Savage Weiner, Sean Hannity, Bill O'Reilly, et al. A ditto monkey is often a raging dullard who can't normally put two syllables together without a paper clip, yet when the topic of their idol's specialty comes up (usually politics), his eyes glaze over and he eloquently spews words you know he couldn't otherwise possibly understand.
