When a person clicks the 'like' button on an uber-gay Facebook Fan Page out of pity for the friend that created the page.
My buddy created an uber-gay Facebook Fan Page for his cat, Fluffy BunnyTaco. He blasted this page out to all of his friends in hopes that they will 'like' the page. Even though his page is uber-gay, I clicked on the 'like' button anyway out of pity. It was a total Fan Page Pity Like.
