Fictional reference source for information of a suspicious or questionable nature. Often provided (sarcastically) in response to hearing some "bullshit". Can be helpfully offered as the source when one hears something that is obviously bullshit.
Me - "I read on this website that he snatched some guy's eyeball out with his fingers. Then he gave the dude first aid AND charged him for it!"
Her - "Really, where did you read that? On bullshit.com??"
