knoll-it-all 

A extremely arrogant, self-centered person who claims at every turn to know more about everything than anybody else in the world. To the point those who had to put up with him were known to wish for a small grassy mound and a couple of eager Cuban mercenaries.

Bob was an avid yet arrogant vintage car collector. His constant and annoying claims he was the expert on every 1963 Lincoln model made led to his being referred to as a knoll-it-all.

knoll-it-all 

A politician so abhorrent you have to have a hidden desire to see his demise at the hands of a couple of Cuban ex-mercenaries perched on a grassy hill using aged Soviet-era rifles.

Self-centered Bob broke all the rules getting elected. He was out for only himself. He made lots of enemies. Some called him a knoll-it-all in the deepest conviction that karma would solve all their problems without human intervention.
