A nickname given to a president (or any other senior authority figure) who is clearly incompetent and completely ill-suited to his position of power but still manages to maintain at least some form of likability factor.

This expression became popular during the early years of the George W. Bush administration.
All hail President Chimp! He may be incompetent but he sure does make us smile! Haha! Did you hear what he just said?
