There Goes the Irony occurs when a person takes a liking to a show or game based on a quality that is usually considered culturally unacceptable, often effeminate. While the initial story is that the show or game is liked for purely ironic reasons, the person soon begins to enjoy it legitimately, and the principle that was initially enjoyed only ironically becomes one of the main points of appeal.
The game provides an opportunity to escape from culture's ideas of what is and isn't acceptable. It's sheet amount of love and innocence can easily overwhelm.
The best example of this is My Little Pony: Friendship is Magic.
Other examples include Robot Unicorn Attack, The Powerpuff Girls, and Spongebob Squarepants.
