a clueless person, most always lacking even the most basic social skills. a doofus often thinks they are a bit smarter then everyone else.
when a doofus makes silly comments at the dinner table and everyone rolls their eyes they think everyone got something in their eye at the same time.

A doofus does not understand why you are not fairly impressed by this.
