Lady Gaga Disease is when a normal person listens to Gaga's music only once and then they need to learn more about her. After they discover new things about Gaga, they start liking everything about her. Then they start getting protective of Lady Gaga and they form into 'obsessed fans' into Little Monsters.
These 'Little Monsters' think that everything Gaga does is cool, when obviously it's retarded and weird. They start liking her personality, actions, looks, speech, singing, acting, dancing, and everything else. While they're distracted by this 'perfect "woman"' (I just threw up a little when I typed that) they are completely unaware that she's a disgusting mutant freak.
