A term used on fans (in most cases, a male) that can not be pleased with anything about a fandom.

Be it Anime, Sequels, Reboots, Games, Books, Movie adaptions of books, ect...

A Unpleasable Fanboy can always find something wrong with anything you like.
Dude, Tom was being such a Unpleasable Fanboy when we went to watch The Dark Knight. This is the last time I go to the movies with him.
