Egomaniac 

1)A self-absorbed waste of oxygen who expects us to grovel at their feet like the unwashed masses they see us as

2.) Someone who talks just to hear themselves (because no-one else will listen)

3.) Someone who posts definitions of their name because they think people care who they are.

4.) The French.
(Unless their country is getting its ass kicked by some invading foreign army then they beg on hands and knees)

5.) US magistrate judges I don’t know if you ever seen one in court but the bastards think they’re GOD (especially when they presiding in mediocre unknown little hic-towns or suburbs)

ergomaniac 

Someone obsessed with finding the placement of items in their immediate surroundings to obtain the maximum comfort and convenience.

Most men are ergomaniacs during March Madness - the couch is used for reclining, and the table has to make the perfect footrest. While reclining, they must be able to reach 5 types of snacks, 2 types of food, 3 desserts, and 3 electronic remotes. At the same time.
